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.
Ear Worm: The title song. Listen to me girls, watch your P's and Q's...
Les Yay: Tons of it. It's a girl's boarding school movie - it's required.
Marty Stu: Paul Anka. He's a very nice guy, but is able to out-tough talk Silver. Of course, your definition of "nice" may vary with his treatment of Serafina.
Moral Event Horizon: Fred, when he decides to kidnap a 15 year old girl, take her to Mexico and rape her, and (it's implied) prostitute her.
Values Dissonance: Well tons, but most shocking to a modern audience is that Paul Anka and Mel Torme were once considered attractive.
Paul Anka telling his stalker that they'll always be best friends, and that he'll hang out with her someday - obviously lying. Talk about Kicking The Dog.
Given that stalking was not as well-understood at the time, and that Paul's character was presented as well-meaning, he probably wasn't lying. He was trying to reframe her concept of their "relationship" into something less extreme, to where she wouldn't still be stalking him, but also wouldn't feel abandoned (and suicidal). Sure, by today's knowledge, it was a stupid idea, but back then it wouldn't seem so idiotic.
