These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternative Character Interpretation: Depending on your viewpoint, Mother Gothel either cares nothing for Rapunzel herself, only her precious hair, and cynically manipulates the girl in order to control her, or genuinely does love Rapunzel but has a warped fashion of expressing it. Word of God states that she does love Rapunzel... as a possession, in the same way you might love a "shiny new sports car."
Her true nature is pretty clear in the "I love you more" sequence. When she says "I love you most," she kisses Rapunzel's hair. In general, she has a tendency of stroking Rapunzel's hair whenever they're close together or in an embrace.
Angst? What Angst?: Rapunzel has realized that her life is a lie, that her maternal figure was exploiting her and possibly never loved her at all, and has witnessed the death of both her maternal figure and her boyfriend, probably thinking their deaths were her fault (her boyfriend got better). Still, she's happy and it's implied that these incidents never did anything permanent to her. It's possible that she never even thought about them again.
Award Snub: It lost a Golden Globe to Cher!. And why did this film have to come out in the same year as Toy Story 3? It wasn't even nominated for the Best Animated Feature Oscar.
Draco in Leather Pants: Mother Gothel has quite a committed fanbase, which can get slightly over-enthusiastic in either downplaying or defending her actions throughout the movie. While she may have sympathetic motives and/or backstory (and that tends to depend on fan theorisingor guesswork rather than what's presented in the movie proper), she's nevertheless consistently portrayed throughout the movie as vain and selfish, a child abductor, an emotional abuser towards that child and utterly ruthless (to the point of a clear willingness to commit murder) in her desire to keep that child all to herself.
See 'Award Snub' above, then think a bit about who Mother Gothel looks like.
There was a Running Gag in the fandom that Flynn looked like Ezio Di Auditore (not to mention he also likes running on rooftops and trying to seduce women). Flynn's voice actor, Zachary Levi, dressed as Ezio during the intro to the 2011 VGA's.
The symbol◊ of the kingdom Corona also looks quite a bit like Princess Celestia's cutie mark◊.
Amanda Seyfried is commonly cited as the actress who most matches Rapunzel in real life. Later, when Les Miserables (2012) came out, Seyfried's first song has her with her hair in a plait, singing about how her life's begun and how she's been kept away from the outside world by her single parent.
A girl with magical blonde hair and a dark-haired villianess wanting to keep that power all to herself. Are we talking about Tangled or Lady Lovely Locks?
Magnificent Bitch: Mother Gothel upgrades from standard Manipulative Bitch to this in her dealings with the Stabbington Brothers. They're murderous brutes and this woman with no magical powers whatsoever doesn't flinch when they pull their swords out, calls them out for squabbling over a tiara and uses the right means of motivation to get them to help her.
Moral Event Horizon: Depending on your view, Gothel may have crossed it when she kidnapped an infant girl to maintain her own youth. After kidnapping her, she abused her emotionally to control her. It worked so well that Rapunzel freaked out once she sat a foot outside the tower. If that isn't bad enough, she killed Rapunzel's boyfriend in front of her eyes and immediately blamed Rapunzel for his death.
Mother Gothel's death, she rapidly ages and crumbles into a pile of dust. The concept art for that scene shows her death in even moregraphic detail.
The whole idea of psychical and emotional manipulation of Mother Gothel. For example, merely setting a foot outside causes Rapunzel to freak out and consider herself a "bad daughter" and an "ungrateful monster" (when she doesn't dance around happily anyway). The idea of a treatment that reduces an otherwise sunny and upbeat girl into a ball of neurosis and fear is a nightmare fuel at its best.
Mother Gothel singing the healing incantation at the beginning of the film is also kind of creepy. The way her voice gets younger as she does, and the way she's whisper-singing it the whole time, is unsettling.
The way that Gothel, at the end of "Mother Knows Best", tells Rapunzel to never leave the tower is creepy in a way that can't quite be articulated.
Gothel's "You wanted me to be the bad guy? Well, now I'm the bad guy..." is creepy because she's still being passive-aggressive and not accepting responsibility. She is not acknowledging that Rapunzel doesn't "want [her] to be the bad guy", she flat out thinks Gothel is the bad guy. And, let's face it, she's entirely right too.
Near the end of the film, Gothel dragging Rapunzel in chains toward a trap door in the tower as the girl kicks and screams through her gag, boyfriend dying on the floor a few feet away.
Paranoia Fuel: Your mother doesn't love you. In fact, she's not even your real mother. She's a woman who kidnapped you as a baby and raised you to be completely dependent on her. And she's willing to break your heart and kill your friends to control you. Love you, mom!
Gothel apologists are claiming all the problems in the movie were the fault of the king and queen for destroying the flower in the first place, even though they didn't know that it could be used without consuming it, and Gothel, who they didn't know existed because she herself never came forward, was the only one who could have told them how.
There are those who decry the king's 'selfishness' in taking and destroying the flower by having it made into a tea, thus destroying its ability to heal. Said 'selfishness', it should be remembered (since these people don't seem to), is prompted by nothing less than trying to prevent his wife and unborn daughter from dying.
The Captain of the Guard often falls victim to this trope. In various fanfics, he turns from a relatively well-meaning (if not very competent) soldier to a sadistic asshole who kidnaps Rapunzel solely to spite Flynn.
Shown Their Work: Gothel is an uncomfortably accurate portrayal of an emotional abuser, for those familiar with them.
Strawman Has a Point: Mother Gothel's condemnation of the world, for some, doesn't stray too far from truth.
Mother Gothel: The world is dark, and selfish, and cruel. If it finds even the slightest ray of sunshine, it destroys it.
As with Frollo, though, it's hypocrisy since she may well be describing herself here.
Tainted by the Preview: When the first trailer hit theaters, many people were put off since there was so much focus on Flynn and so little on Rapunzel when the movie was clearly about her. There was also how slapstick and Shrek-like it seemed (not to mention the movie title being Tangled). The strong week-to-week holds of the film spoke volumes about the terrific word-of-mouth from those who did see it. Not to mention them continously playing P!nk's "Trouble" through promotion, when it wasn't part of the original soundtrack to begin with.
Ugly Cute: The Big Nose Thug. His part in "I've Got A Dream" when he describes all his less than flattering physical attributes is a Lampshade Hanging of this trope — especially the part where he sings about a girl loving him.
Unfortunate Implications: The whole changing from 'Rapunzel' to the gender neutral 'Tangled' for fear that little boys would refuse to watch anything with a female presence in the title. Because, you know, the reason The Princess and the Frog didn't do as well as Disney'd hoped was totally because it had 'Princess' in the title.
Unintentionally Sympathetic: Mother Gothel to an extent. When you keep in mind that she only does the things she does in the movie because she is terrified of dying, it makes her actions seem understandable. Not justified, mind you (controlling and destroying others' lives just to preserve your own is horrible), but nevertheless worthy of some pity. As noted above, this is a matter of intense debate in the fandom, which many raising the question of whether it is so much fear of dying that Gothel suffers from, or the rather-less-sympathetic fear of simply growing old and losing her looks.
The hair. Pixar may have created the program for hair for Monsters, Inc., but programs were written for Tangled (which took six years) to make it more realistic. Thus, every single strand of hair in this film is animated in a believable way.
Win Back The Crowd: Tangled finished the job that Disney started with The Princess and the Frog for being relevant in the animation industry once again, outside of Pixar's shadow. Both critics and audiences loved it, and it became Disney's second highest grossing film ever.
