My biggest takeaway is that this trailer makes it feel very much like a traditional Zach Snyder film. I love Man of Steel, but it was so unlike any of his previous films. This trailer makes Batman v. Superman feel very much at home in the cinematic aesthetic of 300, Watchmen, and Sucker Punch.
Other random thoughts:
-I love Alfred's dry sense of humor
-In terms of fighting style, this cinematic Batman is the closest I've seen to match the comics.
-I love the interplay between Bruce Wayne and Wonder Woman
-The final shots in this trailer make me feel like I cannot wait to see it.
