Finally made it to the theater to see BvS last night. My thoughts echo a lot of what's already been posted... Batfleck and Alfred are great, there's too much trying to happen in the way of story (and it never all really comes together), and the file intros of the other Justice League members is pretty lame. I didn't dislike Jessie Eisenberg as much as I thought I was going to based on the trailers, and I agree that it's more a problem of how the Lex was written than it is with his performance.
Super excited for Suicide Squad, and I also read an interesting theory that Leto's Joker is actually a fallen Jason Todd. Don't think this will actually end up being the case, but it was an interesting thought. Evidently there are a couple bullet holes in the defaced armor in BvS that match up with what looks like bullet wounds on the Joker. It would also make sense in light of Affleck's line about how nobody stays good, and explain why Wayne Manor was in ruins (if Joker had formerly been Robin, he would know who Batman was and where he lived).
