I agree about the animations. And I agree with the poster above who said the animations looked like Parkinson's disease. I actually had to exit the game after my first few minutes because it created a bad first impression for me.
But I came back to the game and now I am gradually getting used to them. I still think the animations look amateurish but I am enjoying D2 very much despite that. A good game is more than the sum of its parts and D2 is no exception.
