300 is easily my favorite Snyder movie. I just love the setting, the action, Butler and co, and the swagger that movie had. It was nothing more than a popcorn action flick and it excelled at that.
I know most will be very disappointed if BvS is on the same level, but honestly that's all I really want from it. Snyder tried and IMO failed badly at making a superhero movie with the depth and breadth of the TDK trilogy, so all I want from him is what he does best. I'm perfectly fine with BvS being a popcorn action flick with a badass, comic-booky Batman in all his dark glory, Superman and WW with their powers unleashed, and a decent story, with the type of swagger 300 or The Avengers had. And it's already a given that everything is going to look awesome.
I'd expect more of a TDKT level of sophistication from Affleck for the solo. Speaking of the TDKT, the movies have been playing on TV this week, and every time I catch even a glimpse, I just have to keep watching. The movies are only getting better with age, imho. Once you get past all the fanboy nitpicking, the expectations, the angst, etc all that's left is some damn good television.
