I saw the trailer twice. Pretty fucking awesome. It's not a brilliantly edited piece of promotion like Man of Steel trailer 3, but it got the job done. I like everything that I'm seeing. Lex looks like a standout.
Yeah it needs some Zimmer for sure, and better editing. Trailers can give quite different idea how movies is, but this is was not best trailer.
One thing is for sure, for me, Lex is cast bad.
