I...focking love this. My relationship with DCEU movies has been an inconsistent love-hate affair, one that leaned more towards hate in it's BvS phase, but I have to say in between this and Suicide Squad, my hope's been rekindled.
It seems to have humor in it while at the same time retaining the grim and dark characteristics of a typical DC flick, which I think is what Snyder should have gone with in it's first two entries. It acknowledges and is even willing to poke fun at the character's mythologies, instead of riding their d!cks for two hours and a half. It's perfect.
Only issue I have with it is that it seems to be claustrophobic, too tight and too closed to be a major superhero team-up, but I had the same issue with Civil War's first trailer and we all know how that turned out. So it's really not even an issue. I know this is early footage. Also, I felt that Flash's costume was a little bit weird, but then we didn't get to see much of it. I hope Superman makes an appearance sometimes in the second act or late first act, because the squad feels incomplete without him (and Superman's absence could also be why I feel the film's too isolated).
Overall, I'm so looking forward to this. 2017 is gonna be one of those years, man.
Edit: Batman saying "I hear you can talk to fish" to Aquaman. Priceless. I expected The Flash or one of the other comedic reliefs to point that out, but I like it how Batman's become the Tony Stark of the DCEU.
