Which movie did you like better?I saw both on cinema and I'd definitely say BvS is my clear choice. The only thing I was disappointed about was the cutting/editing of the movie, they should have kept some of the deleted scenes because it got messy sometimes. Other than that, the CGI & acting was very well done, I loved Ben Affleck as Batman same with Gal Gadot as Wonder Woman. It also had bada$$ soundtracks.
AoU disappointed me, I was looking forward to see Ultron as a villain in a movie, in the trailers he looked intimidating like he should, but it seemed like they took his best parts in the trailer because in the movie he was a complete joke.
