Here's my breakdown man,
1. Third person shooter w/ some RPG elements.
2. Quests that are like WoW(ie. Kill XX, Get XX Items, Go to XXX), which in my opinion don't work that well for an ARPG.
3. Melee feels kind of generic, you stand still while attacking. You cannot move and attack at the same time.
4. Tilesets and enemies get a bit repitive after awhile.(ie. You will have dejavu in Act 5 with the same Zombie in the same Tunnel you killed in Act 1)
5. In between Act cinematics are pretty horrible. Act 1-2, a stupid floating book and dialogue. Rinse and repeat till Act 5.
6. Bosses are a bit lackluster. No real storyline behind them, just leave your finger on LMB and strafe.
It may seem like I'm bashing the game, but its not that bad. Its a mindless Hack-n-Slash RPG with a pretty good loot system.
Definetly try the DEMO before you purchase.
BTW, its 40 bucks at CircuitCity and Amazon.Com.
