OK, my rambling thoughts…. I went in to BvS with rock-bottom expectations, and it ended up exceeding them...somewhat. I was expecting a 2 (out of 10) and it ended up being about a 3. Affleck wasn't bad, though he, like many of the characters, wasn't given much material to work with. I loved the scene early in the film of Bruce Wayne in Metropolis trying to save people; I dearly wish there had more of those types of scenes.
Eisenberg seemed like he walked right off the set of The Social Network or Now You See Me or Adventureland or Zombieland, but even more painfully awkward, if that's possible--if he indeed has range, I haven't seen the films where he's proven it. But the film did hold my attention throughout, even if its messages were more heavy handed than Zootopia and Happy Feet combined. The first half or so of the film proffered intriguing ideas, only to either drop them entirely or over-egg them.
Snyder gave up on the incessant sudden zooms that plagued Man of Steel, which I appreciated. However, his visuals weren't as audaciously visceral as I was expecting--I mean, Snyder's talents don't lie with emotional character moments, but at least you expect his images to be somewhat captivating. And I suppose they are, to some extent. But when you have folks like George Miller and Matthew Vaughn delivering exhilarating action
and characters you care about, you've got to offer more than just shots that travel with characters as they're charging at supersonic speeds, swinging the enemy around like a discus, or being smacked through six buildings. In short, there's not much on the visual side that we haven't seen before in Man of Steel.
The score by Hans Zimmer and Junkie XL was so cacophonous that my ears were ringing by the end of the movie--and it was mixed so loudly in the action scenes as to make Christopher Nolan jealous. (The difference was that you could actually hear the dialogue in BvS because there really wasn't any talking during the action scenes.) I admit I was expecting the music to be even more ghastly than it was, but it was just a nondescript Zimmer score that could have been dropped into any action blockbuster and not seem out of place.
BvS wasn't a great film, but I did end up appreciating bits and pieces.
