My gut tells me that Star Wars is going to be better, but it's BATMAN and SUPERMAN TOGETHER IN A MOVIE! I have to vote for it!
1. Batman V Superman
2. Star Wars Episode VII
I'm apprehensive when it comes to Whedon. I wasn't a fan of how he wrote the Avengers as children. Nor was I a fan of Nick Fury's patronizing, with his motivation of his fanboy agent dying, despite the fact that Tony's whole motive in life is saving the world and protecting people after his inventions were killing innocents, Thor whose a warrior that probably lost hundreds of allies in war, or Steve whose a soldier whose whole purpose was to help people and fight Nazis who were far worse than Loki, or Bruce who sacrifices his whole livelihood so no one gets hurt. I was bored of the mindless fighting of drones in the first movie, so I'm worried from what I heard about Ultron. I hope it's good though, but it might just not be for me. I couldn't stand Firefly, so I must be missing something when it comes to Whedon's writing.
I love Iron Man and Spider-man 2, and enjoyed Guardians , so I'm fine with superhero movies with heavy comedy. I just can't stand Whedon.
