At this point in time, I trust Zack Snyder's handling of Batman more than Frank Miller's
Dude, is that 80's Frank Miller, or 2000's Frank Miller ?
80's Frank Miller would write a Batman story that people would be
talking about in 50 years time. ( IMO DKR and BM Y1 are the best
Batman stories ever, and I really liked the O'Neill Legends of the Dark Knight, and the current stuff Snyder's been doing with the Owls,
but it's never topped Miller's immortal stories from the late 80's ).
2000's Frank Miller would write a Batman that we'd spend that long trying to forget. IMO.
Now, having said that, I think that Miller could write a pretty decent Superman story. It would have been interesting to see what Superman, Wonder Woman and their daughter Lara would have done after the events of the Dark Knight Strikes Again.
Although I didn't like DKSA in general, more execution of the ideas than the ideas themselves, I liked his depiction of Superman in DKSA , as guilt-burdened and browbeaten (sort of the next logical step downwards after the conflicted Superman of Dark Knight Returns) but eventually rediscovering his inner hero, or something like that -and then kicking ass.
But yeah, the way Miller has been going, he's not the guy to bring Batman back to the screen - well not unless he rediscovers his old form. IMO.
This is what I'm talking about
