The Marvel Cinematic Universe has been one of the most successful franchises in cinematic history. With over 30 movies under its belt and a number of TV series, the franchise has pulled in billions of dollars within the last decade and elevated a number of actors to stardom. Using the legacy built by Marvel Comics' 80 years of history, the franchise has adapted its characters well. Sadly, this hasn't always been the case for many villains, whose reinterpretations have hurt rather than helped their respective movies.
