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.
No Disney villain evokes this more than Mother Gothel. Did she only care about Rapunzel's hair and just pretended to be a doting mother, or did she come to genuinely love her in the 18 years she raised her? Rapunzel's hair is more important in the end, but Gothel does small things that make one think twice like her "I love you" "I love you more" "I love you most" game and her surprising Rapunzel by cooking her favorite food. Fans are still debating.
However if you pay attention, when she says "I love you most" she kisses her forehead. This could be taken that she loves her Hair most.
Or she's just that good of an actress to fool the audience with a rather convincing performance. It helps that she happens to have a lot of very subtle hints.
It can also be interpreted that Gothel also wanted to take Rapunzel away forever because she was afraid Eugene would, since her plan to get Eugene to dump her failed. Still though, it's mostly for the hair.
Rapunzel is portrayed as the hero, but in all honesty she doesn't leave to get away from Gothel, rather because she wants to do something she was forbidden to do, and she even admits it would be wrong to do this anyway.
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.
Broken Aesop: Doing domestic things (baking, sewing, cleaning, pretty much everything homemakers do for their families on a regular basis) means you don't have a life. However, these are wonderful hobbies and careers when it's men doing them.
Draco in Leather Pants: Mother Gothel has quite a committed fanbase, which can get rather 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 more 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.
Fridge Brilliance: Rapunzel displays near superhuman strength in her feats of derring-do with hair and frying panó because she's spent most of her life building her arm strength hauling Gothel up a 70-foot tower.
Fridge Logic: Gothel pretty much delayed the inevitable with kidnapping Rapunzel. Rapunzel's hair has the power to keep Gothel young, but not herself. If Eugene never found Rapunzel, she would have died of old age and Gothel would have as well.
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.
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 villainess 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.
Moe: Rapunzel. Just look at her! Especially when she laughs. She's more cute than beautiful, and even has a little overbite and a lisp that adds to her cuteness rather than subtracts. Additionally, part of the way through Gothel's Villain Song, "Mother Knows Best" features Rapunzel huddled up in a small fort made of her own hair. It is quite possibly one of the most adorable things in the entire movie.
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.
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. You just want to cry watching Rapunzel whiplash between ecstatic happiness and the depths of depression when she finally leaves the tower, which is an accurate (though time-compressed and somewhat played for laughs) depiction of someone trying to separate themselves from an abuser.
Signature Song: The soundtrack overall is great, but special mention has to go to "I See The Light"
Strawman Has a Point: Mother Gothel's condemnation of the world, for some, doesn't stray too far from truth. As with Frollo, though, it's hypocrisy since she may well be describing herself here.
Mother Gothel: The world is dark, and selfish, and cruel. If it finds even the slightest ray of sunshine, it destroys it.
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.
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.
