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.
YMMV: The Nutty Professor
Adaptation Displacement: Chances are, if you mention this movie to someone, they're going to think of the Eddie Murphy one without realizing that the first version was in the 1960s.
Idiot Plot: In The Klumps there was literally no reason Sherman couldn't tell Denise what was going on.
Nightmare Fuel: The scene after Sherman proposes to Denise. They go out to see the movie Cape Fear, where they hear an obnoxious guy smoking a cigar and laughing too loud for them to enjoy the movie. When they politely ask him to stop, he turns around to reveal himself as Buddy Love. This gives Sherman the most epic Oh Crap look on his face. The music in the scene makes it even more scarier than funny.
No Yay: The hamster and Dean Richmond, who both hint at being interested in continuing their relationship.
Signature Scene: The kid flexing during the Dinner Scene in the 1990s version.
Tear Jerker: The scene in the first film when Sherman is being picked on by the comedian Reggie. We pan into Sherman's hurt face and sad music plays. Anybody who was ever bullied would know what that feels like.
