I agree - IMO 2K4 was better. CPU AI at times really took a dive thanks (I would guess) to the new profile system they put into the game. 2K4 gave me some fantastically realistic games, I gave up trying in 2K5 after wasting hours on sliders and global roster edits etc to patch over the newly introduced AI deficiencies.
As for this video, looks about what I expect. The game is still far from flowing like real life - the way the engine seems to struggle transitioning from one animation to the next, particularly on contact, is definitely noticeable. But even the slightest mishap would be in a video like this with those angles. There's a difference in mindset watching a video compared to playing a game. Yes, insanely realistic animation would probably be amazing, but it's almost a case of what you don't know not hurting you - you deal with it. When it comes down to it, AI far, far out ranks animations and aesthetics for me.
