Either people are trolling, have way too high expectations or simply haven't played the game at all yet... my beta experience so far has been awesome, the gameplay is incredibly smooth and the entire atmosphere is just perfect (what comic looks are you talking about? cant see it).
The game has so many amazing details that you don't notice immediately or just take for granted. For example when you start playing a barbarian, have you noticed how f mighty the character feels? The spell animations and sound, coupled with the fluent gameplay makes me want to slay hordes of mobs nonstop
