I’m loving the responses, but I think “favorite” and “boring” are being used rather loosely. 
I think some people are also taking the word “describe” pretty loosely. They’re describing a single scene in a movie rather than the movie as a whole.
For example, “A son reluctantly takes over the family business” is a description of The Godfather. But “A guy pets a cat” is a description of a single scene in The Godfather.
