Spider Fan 14: To me, the fact that "Too Young" basically had PB and Finn join up and bully the technical son of PB. It was painful to me when you add in the Fridge Horror of it all. And this may just be me, but Lemongrab seemed very mentally/physically impaired, and this makes me want to cry now, because I have Aspergers's Syndrome and know what it's like to be picked on for being considered awkward and freaky. Yes, he was being a Jerkass about the situation at hand, but there had to be better ways of dealing with him than how PB and Finn did it.
DeepC: The ending to the Adventure Time episode, "Wizard Battle". Now I absolutely love this series with a passion and the beginning and middle of this episode weren't all that bad. Now why do I loathe the ending so much? Well allow me to explain the beginning first. The whole episode starts of with Finn and Jake watching a battle amongst wizards. Everything is going great for them until they see the Ice King cheating so he could win the grand prize, which is a kiss on the lips from Princess Bubblegum. This motivates Finn to enter the Wizard Battle disguised as a wizard, stop the Ice King, and kiss Princess Bubblegum. While they fight, they come across a mediocre wizard named Abracadaniel, who wanted to fight, but does not want to kiss Princess Bubblegum. So Finn decides to help him win in order to save Princess Bubblegum. As the battle progresses, Abracadaniel gets even better with his magic and manages to defeat the Ice King. Now this sounds all fine and dandy, correct? Well here comes the Dethroning Moment of Suck; when Abracadaniel and Finn are the only ones left, Finn forfeits immediately, which meant that Abracadaniel won. With his newly developed confidence, Abracadaniel decides that he does want to kiss Princes Bubblegum after all. However, due to the "Power Of Love", Finn goes batshit crazy and screeches at Abracadaniel in a way that can be considered OOC, immature, and downright mean. This causes Abracadaniel to fall over, and even though it appears that the announcer is about to call him out for that, Finn still wins! Later, Finn is stressed out about hiding his feelings; now, it's understandable that you're stressed about hiding your feelings, but what about having regrets for the way you screamed at Abracadaniel, pulverized his new-found confidence, and hurt his feelings?! Later, Finn reveals who he is in front of Princess Bubblegum. Now does he get any sort of scolding or punishment from this? Well, he does get a slap on the face for cheating, but he still wins the prize of getting a kiss from Princess Bubblegum! Not only did Finn cheat, but he acted like a Jerkass and started staggering near Mary Sue territory. So I guess if I act like a screechy and jealous guy, I get what I want and there are hardly any consequences for it!
TheyCallMeFluffy: I like "Wizard Battle" and thought Abracadaniel was adorable for a bit, but God I hated how he was only Camp Gay (right down to his power being rainbows) and turned off to the thought of kissing PB when he was scared and wimpy. When he gains confidence and starts winning battles the campness goes, he starts "acting like a man" and suddenly looks forward to kissing PB. I like to think the writers were taking advantage of a stereotype to set up Finn's jealous turnaround when he'd previously helped Abracadaniel and they probably weren't actually advocating thinking of camp/gay men as just weak and in need of fixing (hopefully), but it's a huge Berserk Button and a gag I wish would just die already. I'd kind of hoped they were above playing it straight and I skip the part right before the power shriek when I re-watch it because it ruins the carefree mood Adventure Time usually has me in.
Filby: It mostly just bothered me that Finn and Jake just kinda forgot the wizard training they got back in the season 1 episode "Wizard", especially because their teacher and two other students from the same wizard school were there.
TornadoTomato: "You Made Me!" would have been a fantastic episode if it hadn't been a completely disgusting Karma Houdini for Lemongrab. This man acted like a monster for a whole episode, was a spoiled brat, tortured children, tried to electrocute his creator (who was being extremely kind to him...) and yet, he got exactly what he wanted, he was not punished or reprimanded for anything he did wrong. Even Princess Bubblegum justified all of his disgusting, torturous, cruel actions with "Oh, he's mentally disturbed, so he gets a free pass on just acting like a downright rotten person." Lemongrab justified all of his horrible behavior with "Princess Bubblegum made me this way, so this is how I'm supposed to act." I was one of the fans who felt sorry for Lemongrab during, and after, Too Young, but "You Made Me" made me lose almost all of the fondness I once had for this character. The moral of this story was this: "If you spend your life acting like a monster and hurting your family and those who care about and worry about you, you will get exactly what you want, and you will eventually find true love."
ading: For me, the DMOS for Adventure Time is the episode "His Hero." Finn and Jake meet Billy, who teaches them to be nonviolent in helping people. Throughout the episode, their attempts at nonviolent methods are portrayed as idiotic and just causing more trouble, and in the end they are forced to face the fact that the best way is to punch monsters in the face. So... the moral of the story is "nonviolence is never the answer?" What kind of a message is that?
Flygon Rider: My Dethroning Moment of Suck is the episode "Wizards Only, Fools", mostly concerning Bubblegum's characterization. Normally, she comes off as an overall sane, level-headed, kind, sometimes morally ambiguous ruler. However, this episode tosses that characterization out the window and instead turns her into a whiny, pigheaded, stubborn idiot who refuses to admit she's wrong, thus getting her friends thrown in prison and nearly being forced to kill one of them. And the whole "refuses to believe in magic" thing really rubbed me the wrong way. She lives in a world that's filled with magic (and frankly, needs it just to keep running), she's probably seen magic at work before, and she even used magic in "Five Short Graybles" to make the perfect loaf of bread, but now suddenly she's dismissing all of that? It'd be more understandable if she was the kind of person who wanted people to explore magic and see how it ticked instead of just accepting it at face value, but nope! She now believes that magic can simply be explained away. This wouldn't be so bad (if she considered magic a more advanced form of science), but Peebs goes about it in the most pretentious, stuck-up way possible. In my opinion, this is Adventure Time's low point. The only thing that made up for some of it was the Princess showing off her parkour.
ghosttorrent: "Jake Suit"; not the episode, but Finn's attitude. He basically says he doesn't care that Jake gets hurt when he wears him and this is his brother and best friend. And then he jumps down a volcano, almost killing them.
Tropers/hurpdurp: "Too Old" for completely ruining Lemongrab's character by making him the most unlikable character in the entire show.
Tropers/Mswordx24: Ctrl+V that entire sentence, except replace "Lemongrab" (who I still think is a good character) with "Finn". They turned Finn into a totally selfish and horny teenager. He even lies to Jake by telling him that PB hates him so that it would be easier to flirt with her. Whatever happened to The Hero? The Conscience? The Paragon? The incorruptibly pure hero with an unbreakable moral code? The guy whose "deal" was slaying evil and not finding a girlfriend? Sorry, he's gone. Now we're left with the guy who would rather flirt with his rebound girl than save the lemon people and Lemonhope. In the end, he realizes that he shouldn't be flirting with her, but for the wrong reasons (because older people are "less fun inside"). Not learning a lesson is the cherry on the DMoS sundae, and Finn didn't learn his lesson. I severely hope this is just a major flaw the writers are intentionally giving him so that a giant character redemption pay-off will come later. But we all know it won't happen and Finn won't learn his lesson. He'll just suddenly be dating FP (again) as if nothing happened. Not one of Finn's proudest episodes.
Kashima Kitty: Concurring with the above about "Too Old". I have a pretty strong tolerance for distasteful things, but this episode of Adventure Time made me sick to my stomach. I expected the creators to learn their lesson about Lemongrab after "You Made Me" but it seems they're going out of their way to make him as unlikable as possible. The way he treated Lemonhope was bad enough, but what happened to the other Lemongrab was probably the worst thing I'd ever seen on this show.
fluffything: I agree wholeheartedly that this episode is a mess. However, my biggest issue is that this is yet again another "will they or won't they" dramatic tension episode between Finn and PB. Good gods almighty, can we just move on from this already? It is getting old. Look, I don't mind romance in children's cartoons. But, can we please not have it so forced in? Can we please go back to when Finn and Jake fought against the forces of evil and saved Ooo?
Vanguard1505: I'm with those about Finn on this one. This may be the writer's attempts to show Finn is going through puberty or something, but when such a phase completely overshadows who is meant to be The Paragon of the show, changing him from an Incorruptible Pure Pureness to some really horny teenager who is on the rebound, this only serves to be an awkward and painful distraction. Keep in mind, this was the same kid who refused to crush an ant because it was neutral, and here he is not giving a damn about a single citizen of Lemongrab's when they are obviously being tortured for the tyrant's amusement.
On The Hill: All the downright beautiful storytelling that was shot down with this episode. The Lemongrabs were loud, grating, impulsive, antisocial, and prone to making horrible decisions. They were also fiercely devoted to one another and loved their children deeply. And that's just fine, the narrative used to say. Some people are deeply troubled and need to be treaded around somewhat carefully, but that doesn't mean they're beyond help; and it certainly doesn't mean they can't love. Their hearts are fine... they're just like this. And this is where we end up? To hell with you, Adventure Time. There's Darker and Edgier and then there's just a train-wreck.
Hairy Leg Herpich: My biggest issue with this episode is how distasteful it was. There are just certain things that are too horrible to take lightly and I believe that child abuse is one of those things. This episode was so crammed full of blatantly violent child abuse and domestic violence that I wonder how survivors of these tragedies will deal with having been triggered by the episode. This episode was just disgusting.
D Yellow Madness: In addition to nearly everything anyone else mentioned about this episode I hate that it's like Finn trying to get with PB is the important thing happening & the slow horrific murder of the nicest guy in the building is a background event. They even still portray him as a nice guy so why does Pendleton Ward consider his fate so unimportant? Does he hate autistic people or does he just hate all of his fans? He sure seems to hate fans of Finn, PB, & the Lemongrabs & he seems to hate kids too considering how completely out of place this all is on day-time Cartoon Network. This episode made me go from thinking Pendleton Ward seems like a cool guy to thinking he's a total scumbag. Most of the episodes involving the Lemongrabs are some of my favorites but this episode has tainted 'em for me because they're full of moments that me think "that's some wasted character development" or "I wish I could see these characters without watching the same few episodes repeatedly."
Mighty Mewtron: "Earth and Water" for being too rushed. The ideas behind the episode (the real reason Flame Princess was locked up and the flashback, FP becoming obsessed with honesty, the Ice King temporarily living with Finn and Jake, etc) weren't too bad. However, a lot of the plot isn't utilized as well as it could have been. For example, at the end of the episode, Flame Princess takes over the Flame Kingdom (with the help of Cinnamon Bun), starting a rule based entirely on honesty. The problem with this is that we don't see the action of them doing this! Instead, we watch Finn and Princess Bubblegum saying random stuff and truths in order to access the Flame Kingdom (never mind that the "jokes" include Finn making a Your Mom joke and admitting to hitting a baby in the head with a snot bubble). The first part of the episode isn't too bad, and the idea of learning more of FP's past is intriguing (the baby FP was indeed adorable), but the ending was incredibly rushed and felt a little forced.
My Little Pingas: Not to mention that once again, PB is never called out on her crap. She may have only done it to protect everyone, but locking Flame Princess up without showing any sort of remorse or sympathy when she was a baby, then callously tricking her into being experimented on while claiming she was going to help her was just awful. What makes it worse is that she overheard what FP was talking about and what made her upset, but didn't even bother trying to talk to her about it or make her feel better. She should know damn well about FP's situation with Finn, since she basically put him through the same thing. She knows this now because he admitted it to her in "Burning Low", but even then she only cared about Flame Princess' unstable elemental matrix and never actually apologized to the boy himself! Hell, Jake called her out on it, but it was brushed off immediately! To be fair, she's actually a wonderful character with many good traits. But for Glob's sake, girl, own up to your mistakes.
The Ant 1: First off, I want to make clear that I'll continue watching this show no matter what, actually I pretty much do that with all the shows I watch. But I, for the love the God, cannot stand "Red Starved". Why you may ask? Well, I'll tell you. Jake closes off his friends' only means of exit, eats all of Marceline's red, nearly tried to eat her... and nothing happens to him. He was twokinds of Houdinis.
heartauthor: My original D Mo S was "Another Five More Short Graybles", but I've found myself a new moment that I find more irritating. With all the ups and downs of Season Five, "Root Beer Guy" was actually a pretty refreshing episodes, and definitely one of the better ones I've seen in a while. But then, literally at the last second of the episode, I saw something that actually gave me Mood Whiplash. Earlier in the episode, it was acknowledged that Root Beer Guy was attempting to write a mystery novel, and he had been spending the last ten years trying to write it. At the end of the episode, RBG's life seems to have taken a turn for the better after becoming the head of the Banana Guards, and as we see him and his wife happily going for a walk outside... there's a split-second shot of RBG's typewriter in the trash. Now wait a minute! You mean to tell me that this project that was clearly very important to Root Beer Guy, to the point where it was interfering with the rest of his life, and he had been working on it for ten years, just literally ends up in the trash after one specific series of events? Like I said, yes, RBG's preoccupation with the story and solving the episode's mystery was affecting his real-life relationships (mainly with his wife), but that doesn't mean he shouldn't be allowed to have things he's passionate about. And if anything, at the end of the episode, RBG actually has a story! He could have written about his real-life adventure and let people enjoy that! While it's nice that RBG was able to move forward in his life, as someone who wishes to be able to write for a living, that last second of the episode was not a pleasant sight to see.
UnionMan: While Adventure Time is one of my favorite animated shows, I found the newest episode "Apple Wedding" to be extremely disappointing: Like in "Wizards Only, Fools", Princess Bubblegum's characterization was awful, making her a petty and unlikeable Jerk Ass, who acted like an abusive Control Freak: When Tree Trunks tells PB she does not accept Princess Bubblegum's authority to perform her wedding and insists that she can only be married by the King of Ooo, Princess Bubblegum enrages and later tries to expose the King of Ooo as a fraud... So she enters into King of Ooo's zeppelin, makes it crash into the wedding, declares the wedding between Tree Trunks and Mr. Pig as a "criminal farce" while showing the King of Ooo's outdated wedding officiant license. But then, The King of Ooo pulls out his up-to-date paperwork and accuses PB of breaking into his blimp. Instead of recognizing her mistake, Princess Bubblegum sends the King of Ooo to jail anyway. When the wedding guests protest, Princess Bubblegum sends all of them to jail. Even Finn (who wasn´t even opposing her in those moments). In this episode, PB was shown to be Not So Different to Lemongrab (The way she threw them all in jail after saying "Nope. Shh. Nope. Nope. Nope. Stop talking, go to jail." is reminiscent of Lemongrab's retort: "All of you. Dungeon. Seven years, no trials.") acting in a complete tyrannical manner against her own friends. So what if she released all of them at the end? She shouldn't have put her friends in jail in first place. She doesn't even receive any sort of minimal comeuppance for her completely unfair behavior, and just seemed to confirm PB status as a Creator's Pet in the series. I think it would be very hard for viewers to find her likable after this episode.
Super Saiya Man: Am I the only one who thought that while Princess Bubblegum went too far during the episode, it would have been completely avoided if Treetrunks didn't bite the Jerkass Apple herself? Like it or not, Treetrunks, Princess Bubblegum is the authority in the Candy Kingdom that protects you through thick and thin. At least let her make a speech, or hell, have both her AND the 'King' of Ooo to do the ceremony. That way, PB's ego is satisfied, you get your wedding done, and everyone is happy and we can focus on what was advertised: Finn trying to keep Lumpy Space Princess away from the wedding in comedic fashion.
Tropers/myfriendbob: "Rattleballs" and the game "Explore The Dungeon". Both are pretty much proof that Princess Bubblegum is Josef Mengele. She literally committed genocide and performed non-consentual, painful experiments on living, conscious people. IMO, she's slid into total Complete Monster territory.
Charleston Man: I'd like to point especially to the end of "Rattleballs". It was attempted to pass as Character Development for Bubblegum and that she'd learned her lesson. What it really comes off as is yet another in a long list of Karma Houdinis for PB, coming right on the heels of similar instances in "James" and "Apple Wedding". This case is particularly aggravating because she was downright genocidal in it and yet still got off scot-free. It's like what happened with Lemongrab in "You Made Me", only taken Up to Eleven, and continues to drive home that PB just can't seem to suffer any negative consequences from her terrible actions, nor take full responsibility for them.
supernintendo128: "The Red Throne" was a disappointment. Finn was just... there; he served no purpose other then to be a nuisance to the protagonists and flirt with Flame Princess, who he should've gotten over ages ago. Cinnamon Bun is suddenly badass, which wouldn't be bad if it didn't come completely out of the blue. At least have some buildup. And now he's suddenly in love with Flame Princess. Why!? Talk about a complete Ass Pullinvoked! All this episode did was that it hammered in the fact that Finn X Flame Princess is still dead for now. And why did they have to leave Jake out? He would've made this episode more tolerable. And why didn't Flame Lord force Flame Princess to marry him instead of walking away after being rejected? The writers should at least look like they're trying. They could've leaved that plot point out all together!
Dadstardly Demolition: I truly agree with you. The whole episode to me was just to hammer the fact that they're through. Also, having "Rowdy" Roddy Piper as Flame Lord seemed like a cheap reference in a already weak episode to me. There was only one reason why they brought him in.
Echoing Silence: I agree as well. I like Adventure Time. One of my favorite cartoons. Finn just seems unnecessary indeed in this episode! Especially since they already sank the ship in a previous episode Where FP becomes the Ruler of the Flame Kingdom. Flame Princess tells Finn in no uncertain terms that they can't be a couple again. Finn accepts this, a bit with difficulty at first, but FP tell him they can still hang out and be friends, he just has to be honest with her. Finn happily takes that. And he had accepted that he had fucked up a lot with one of my favorite episodes "Dungeon Train", where Finn goes through some emotional development and realizes that though life is painful, he can't just hide away and he must move on, he got over his breakup. He's gone through that Arc. He's in a better mood. Why oh why did they set him back to the Finn that wants to get back together with FP. Like I said. The Ship was sank!
Mo: Might as well throw in my own two cents on this. First off, Finn almost seems completely pointless to bring along if his behavior during the episode is any indication. All he does is hinder Flame Princess and Cinnamon Bun's mission and flirt with Flame Princess herself, the latter being odd since Finn seemed completely OK with him and FP being Just Friends, albeit with him still feeling a bit sad about not being able to win her back. Still, he shouldn't be this stupid or selfish after all the metaphorical anvils dropped on his head. Second, Cinnamon Bun suddenly becoming The Hero. Had this been fleshed out more, this actually would've been alright. However, this was hindered by the lack of build-up, continuity errors regarding the Flame Shield and the fact that this was at the expense of Finn. I would complain about him confessing his "love" for Flame Princess. However, considering the show's target audience, this could be platonic. Finally, the episode itself just seems like an example of They Just Didn't Care. The characters, as I stated before, aren't behaving right (What reason does Flame Princess have for still being cold to Finn? Didn't she forgive him in Earth and Water?), jokes were mostly dry (Though, I did find Don Jon and Flame King's fight a bit humorous), and it just wasn't fun to watch.
Austin DR: For me, it would have to be "Betty". There's actually nothing wrong with the episode, in fact, I liked it. My only complaint was that the episode was too short. To me, we didn't get to know too much about Betty, and that they rushed the ending to the episode. I wished that they could've had a two-parter so that we could learn more about Betty and maybe more on the Mushroom War, but they simply ended the episode with Betty flying off on a magic carpet, implying that she'll find a cure for Simon. Again, it's not a bad episode, I'm just disappointed that we didn't learn more about her or the Mushroom War.
Tropers/buttprankster: Not an episode, but the second Adventure Time video game, "Explore The Dungeon Because I Don't Know," is this for me. Before I say why, let me just remind you that the game is canon, so everything I'm talking about did actually happeninvoked within the continuity of the show. Because of this, we can presume that the game takes place some time before "Another Five Short Graybles." In the game, Finn and Jake encounter the Lemongrabs, who have been lost and trapped in the underground dungeon. The Lemongrabs tell Finn and Jake that Princess Bubblegum had lured them down there to perform non-consensual, painful experiments on them. The whole time, the Lemongrabs seem to be in pain and they are clearly traumatized, especially Lemongrab 1 who has some gummy thing stuck to him. What the fuck, Princess?! There's "pragmatic" and then there's "unethical." That was beyond unethical- it was just disgusting. To hell with you, Princess. How dare you pretend you don't know why Lemongrab went crazy. It's because you freaking tortured him!
Tropers/Asger: I had to remove my original entry on "Too Old" just to talk about the new "Lemonhope" 2-parter. Oooooh how I loathe this episode. First of all it brings in that Purity-Stu Lemonhope back into the show, ramping him to almost absurd Creator's Petinvoked status with the little yellow turd acting like a selfish whiny brat for a good chunk of the episode while Bubblegum for some reason expects him to be the one to liberate the lemon kingdom. Gee PB, if only you had some sort of hyper-competent army of robot badasses on hand to handle things like that... too bad you casually committed genocide on them. I digress, a half hour devoted to a much loathed character while "Betty" had everything crammed into ten minutes. It comes down to a battle between Hope and the Earl, which ends when Lemongrab 2 takes the Earl's ear plugs, allowing Lemonhope to blow him up with his music. Then the real kicker- Lemongrabs 1 and 2 get stitched into a horrible abomination by PB, and the princess decides to just leave this poor borderline brain-dead creature to live alone (Didn't that end bad the last time?). Lemongrab 2 is given zero credit for his part liberating his people, making his sacrifice almost pointless, and then when PB offers Lemonhope a place in the castle the selfish yellow bastard decides to walk off and put his own needs above everyone elses. And then PB sings a song about just how great Lemonhope is, while we're treated to the grim sight of a desolated Land of Ooo. What a... charming ending. Christ.... writers, please never do another Lemongrab episode, because all you do is lay down more Unfortunate Implications on top of the previous ones.
FromtheWordsofBR: Not to mention, just like what The Mysterious Mr. Enter said about "House Fancy", if you don't care about how much of a JerkStu Lemonhope is in this episode nor everything else Asger said about it, then it's just boring! Very, very, boring! I'm not joking, a show that has been able to turn simple, mundane plots into fun 11-minute episodes actually has made an episode that almost literally put me to sleep. What happened, writers? There's Jumping the Shark, and then.....there's this.
spongebutt: What really hammered the nail in the coffin was the fact that they showed graphic abuse of all of the lemon kids on-screen, and all PB and Lemonhope did was watch passively. And they treated Lemongrab killing one of his children as a joke. Child abuse is not fucking funny! Every day, real children are horrifically abused by their own parents and many of them actually die due to abuse and neglect! This was the one that ruined the entire show for me. I will never watch this show again. It is disgusting.
