12 things we learned from the new 'Batman v Superman' trailer

The second "Batman v Superman: Dawn of Justice" trailer debuted at San Diego Comic-Con this weekend, and it was absolutely jam-packed. 

Clocking in at nearly three and a half minutes, the trailer gives us our first look at the plot of the film alongside a plethora of Easter eggs and glimpses at what the wider DC Universe will look like in the movie. 

Let's dive right in.

They're addressing one of fans' biggest issues with "Man of Steel."

A big problem a lot of fans had was the widespread destruction in the big finale to "Man of Steel." The movie sort of acted like it was no big deal. "Batman v Superman" looks like it's going to take this head on, revealing that Bruce Wayne was at the scene, and he's very, very angry. 

We finally know Batman's big problem with Superman.

Now that we know Bruce was in Metropolis when it was nearly leveled, we learn the personal stake he has in it — one of his buildings was completely destroyed in the fight, and Wayne feels responsible for the people who died on his watch.

This Batman is kind of messed up.

Ben Affleck's portrayal of Batman is the angry, ruthless sort with none of the deep sadness that seemed to haunt Christian Bale. He also seems to take things a bit too far — it looks like he even brands criminals he apprehends!
