Had extremely high expectations for this movie, as did most, but it was one of the most cookie cutter superhero films I've ever seen. This was ironic because the whole plot was supposed to be the opposite of a superhero movie. At the end of the day it was just twitchy superheros posing as villains, aside from Deadshot and Harley Quinn. But those 2 got 90% of the movies dialogue anyway so who knows.
Pros: Production value, good costumes, decent special effects, Will Smith, occasionally seeing Cara Delevigne, decent humor at the end, great soundtrack, some badass action scenes
Cons: clichés, plot, zombies, ending, corniness throughout the movie, didn't play "Purple Lamborghini" -the best song on the soundtrack, pacing was bad; the whole movie felt rushed, the worst joker and Batman, joker felt extremely forced, oh and clichés again because the whole movie felt like a giant cliché
TL;DR:Disappointing, a worse version of the new Star Wars movie adapted by DC
