I just started playing it about an hour ago and they introduced Leo and the wide eyed, unnaturally positive reactions to even mundane tasks (like accompanying The Witcher) is a total distinguished mentally-challenged fellow response. He has crazy eyes too, like, when your able to see the whites of his eyes from the left, right and top. It freaks me the fuck out.
But other than that, I like the hit combo battle system though it sort of feels clunky (I honestly don't mind it though). I can see where some of the hate is coming from. Visually it looks good but the Cinematics and personality of each character is super cool and better than most Western cookie cutter offerings.
The opening Intro is badass too
