I think it looks fantastic. I'm now a little hopeful that Eisenberg will pull off Lex..I really liked what I saw.
So in this trailer you'll see..
Jason Todd's costume (with Joker's message on it)
A creepy/cool Lex Luthor with hair
Batman apparently brands the criminals he captures
Lex creating/discovering Kryptonite
Zod's body
Also, Wonder Woman looks good surprisingly.
