6. Batman v Superman: Dawn Of Justice
Rotten Tomatoes Score: 29%
Batman v Superman: Dawn of Justice has to be the most disappointing and sloppy sequel in the history of superhero movies. Like the one and only redeeming quality about the film was its introduction of Gal Gadot as Diana Prince aka Wonder Woman, who was a true scene-stealer in the film and one of the DCEU's greatest performers.
Rather than giving fans the Man of Steel sequel they deserved, DC tried to rush along its groundwork by introducing members of the Justice League including a new Batman. Not only did the film introduce a new Batman, but this was a Caped Crusader who did not like Superman whatsoever and decided, "Hey, why not pick a fight against the strongest hero in this world because that's what billionaires do."
Yes, I know that is a very simplistic way of defining the movie, but let's be honest, it's not inaccurate. The movie basically pits Batman and Superman against one another because of some light manipulation by Lex Luthor and was such a letdown.
The plot was weak, the storyline tried to do too much, and the actual Man of Steel cast members got lost in the shuffle instead of getting legitimate character development in the sequel.
