The setting of the game is constantly at odds with the characters that inhabit it. Most of the dialogue is just trash. The developers couldn't decide if they wanted to make an atmospheric RPG or a light-hearted one, so as a result we get a game that seems like it should be atmospheric, but all the characters keep saying things like 'An apple a day keeps the doctor away! So go ahead and eat anything that looks like an apple,' and areas with names like Chocolate Park. If they'd gone all the way and made it some kind of surreal parody that would've been fine - but they didn't, so it's not. It feels like a game filled with placeholder dialogue.
On top of that, as phatosealpha said, the game just isn't very good. Despite being made by some of the guys who created Diablo, Flagship seem to have made a game which includes none of the things that were good about that series. The skill tree is a hopeless mess, there's a billion mundane quests rather than a handful of quality ones, and the randomisation of the areas is a joke. Even ignoring its atmospheric failures, the game needed at least a year or so more development than it got.
