DDs2 stairwell hands down. Though I think it's a little over praised for being "One Shot", the seems/cuts are incredibly obvious to me eye and there are a lot of them (S1 hallway fight was way better.), but it's otherwise a really good sequence, and you really feel the amount of effort it's taking Matt to go through these guys.
BvS Warehouse- I actually think this one is cartoonishly over the top (ironic for a film that's trying so hard to be dark and serious). Bats is sending goons flying 15+ feet through the air just with single punches and kicks. Were they fighting in low gravity or something?
