Lots of disjointed scenes that didn't connect, flashbacks that could have been shorter or done away with completely, a lack of real dialogue and just so much they could have made better. BUT...there are also quite a few things that a well-rounded comic fan like The Hubs caught and understood. I ended up enjoying it more than I thought I would, especially after reading the reviews pior to seeing the movie and letting myself get bummed out by them.
Ben Affleck as Bruce Wayne was a pleasant surprise. Seriously.
Wonder Woman joining the fight like she did was THE BEST SCENE EVERRRRRRRR!!!
Holy crapola, I'm not really schooled in the DC universe (my only reference being the Justice League cartoon I use to watch back in college), but the metahumans scene got me so excited!
