All I'm seeing in this thread is randoms who haven't made it past the opening sequence if they've played at all. If you're going to criticize something, give examples other than copy/pasting "it's a rip-off of a 12 year old game!" or "the combat sucks!".
It's been said a million times - it starts slow, picks up the pace fast, until it's almost scarily quick/smooth at high levels.
Granted, animations aren't anywhere near D3's quality yet. The graphics perfectly fit their theme. I think they look rather amazing in-game.
