Eh it has flaws and they're not 'hating' on it as they can at least say why they dislike it, don't recall much of the way of frothing about it here, but oh well.
I'd mainly see the combat being twitchy and stuff like the inventory, QTEs being things people would have found off putting - that last boss fight was rather annoying to me. I enjoyed it overall, am replaying the EE right now off and on.
The map? That's the only puzzle I remember being bloody annoying.
Edit: No, wait, just remembered there was some puzzle of ultimate braindestroyer at the end, somesort of chessboard or something.
No, the cat hair mustache puzzle
