Civil War is this. Throwaway villain convicts a convoluted, illogical plot of vengeance that turns the Avengers against each other that they still fall for, even going against their established behaviors to do so. The Avengers have epic fights and new heroes are introduced. The end.

Honestly, if you've read the summary then you can skip the movie. It's contrived and illogical. Watch clips of the fights on YouTube if you want. This film has little value elsewhere. The Avengers reunite the next movie.
