I love this trailer.
Afleck appears to really nail the role (though nothing is certain without seeing the finished product). Eisenberg's Luthor, while not having the obvious evil businessman motif that I enjoyed from the Superman animated series, seems like a great evil instigator.
I also love the part where Wonder Woman shows up. Wonder Woman is one of the most iconic superheroines and, despite the bondage theme that shows up in her comics, I always looked up to. She hits all of the adjectives that I look for in a superheroine: smart, capable, serious, strong, and sexy.
It was also nice to see the spray-painted Robin suit, hinting that Leto's Joker has killed a Robin, or that perhaps the Red Hood storyline is part of the cinematic universe. I also like it because it shows, even if for a moment, the presence of a bat family (even if it was limited to just Batman and Robin), and I'd love to see a serious Batgirl or Batwoman in the new DC cinematic universe.
I also noticed what looked like a parallel between Batman fighting the Superman soldiers and Batman going after the Mutants in the animated version of the Dark Knight Returns.
There is one thing that sort of got me about the trailer though: I heard someone refer to the actor who plays Thomas Wayne as Jeffrey Dean Morgan, but he looks a lot like Nicholas Cage in that flashback (or maybe that's just me).
