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 Little Shop of Horrors
Adaptation Displacement: Many fans of the musical are unaware that it was based on this movie, and thanks to the Frank Oz movie, people may accidentally rent the Roger Corman version, or try watch it online, not realizing which film it is, and sometimes complaining that it's not the Frank Oz movie.
Nightmare Fuel: The scene in which the plant's flowers open. The cartoonish sound effects did not help.
One-Scene Wonder: Despite his limited screen time, Nicholson's appearance is one of the most popular scenes in the movie. A testament to the popularity of this scene is the fact that it was cut out of the musical, but written into the screenplay of the Frank Oz movie, where the role is instead adopted by Bill Murray, under a different character name.
Padding: Like many Corman flicks, this one has tons of walking scenes... and running scenes!
