Finally watched this video. The detail in first segment as the player's gliding through the city is impressive. Even if this was merely "captured" on a PS4 devkit, it's still really great to me.
Everything else looks great except for the combat. The series has always had little trails streaming from Batman while he flies around a room, but here they're even more pronounced and it looks odd. It seems like Batman's been sped up, but it could just be the upped fidelity/more realistic look clashing with the unnatural speed it's probably better to play than it is to watch. There are more abilities showcased like the mid-combo smoke bomb and the "critical" moves, which is good. The attack hits don't have that thunder sound effect from past games which may contribute to it seeming insubstantial to me. That sound effect lacking in Origins made it evident that it just made the final hits seem more satisfying. Here, the combat seems the least impressive thing being showcased, and I felt the same with the previous "Officer Down" gameplay trailer. The Batmobile gameplay looks comparatively exciting, but that could be because it's something new whereas combat in this series isn't.
