As far as Snyder making BvS like DKR? I don't know where to find it, but there's a video compiling all of Snyder's interviews, where he SPECIFICALLY states that although he is a fan of DKR, he's using it as a template of what NOT to do with Superman in his movies.
Don't remember the exact quote, but he basically said that this movie will not be "DKR the Movie."
I sincerely hope that is true. Nothing about the movie would please me more than that.
