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.
Cliché Storm: Sister Act 2's plot is basically the quirky teacher that the strick authority figures don't get her style of teaching, but she helps the troubled inner city students believe in themselves, then proves all the stuck up authority figures wrong, and saves the school from the corrupt corporate executive, by winning a choir contest.
Genius Bonus: There are a lot of Catholic in-jokes. For starters, all the songs the sisters jazz up are actual Catholic hymns.
Heartwarming Moment: Delores and the Reverend Mother at the end of the first film. Yeah. That scene.
