This list of mine ranks the DC Extended Universe Movies from top to bottom. This list will be ranked based on taste/preference and not necessarily dependent on its rating.
Actual Ratings (for those who are rated 10): Because Trakt does not have option to press "favorite" on movies and TV shows, a movie or a TV show that is ranked 10 is considered a favorite on trakt's database. So here's the actual ratings for the MCU films that are rated a 10 on Trakt from me.
Batman v. Superman: Ultimate Cut: 9/10 (real rating: 8.5)
All of the unreleased DCEU movies will be ranked based on anticipation starting from the 3rd rank.
