If you like hack and slash games, it's under appreciated, yes, but still not great.
However, I tend to like games where you can take out ranks of enemies in one swing, which is something you can do when you go into your special, damage enhancing mode. The regular combos are neat at worst, but more importantly they're effective, so I don't understand where people get off saying that the normal attack is better than combos. If it sounds a little over-powered, that's because it is. In a majority of the battles, your enemies do not stand a chance against you because even if their hits can hurt you a lot (and they can), they never have the chance to hit you, and certainly no chance to hit you twice considering their expected lifespan. There's almost nothing you can't get through by turning on your special mode: any enemies in a 200 foot radius will be dead in seconds. Not to mention that your enemies' commanders seem to have this same power, yet don't seem to kill your troops like you do theirs. In spite of a good chunk of the game being easy, there are some scenes that made the game for me. At those points, you cannot simply wipe out your enemies in a few swings by dashing across the battlefield.
The other parts of the game are really undeniably bad. Your troops don't help out (not that they need to) just like most other games where you command a squad or army. And God... the voices... they are so annoying and loud. They usually don't even have anything special to say and I don't want to hear their awful voices anyway even if they do say something that has to do with the plot. It's something that I turn the voice volume down to the lowest setting for so people in the other room don't come in asking, "What the hell is that?" Then there's the maps -- you can't go outside of the path nor even jump onto rocks. Not that that's specific to this game, but that doesn't stop it from being annoying. It feels even worse when you consider how much your attacks move you across the battlefield, and yet, small rocks stop you from going further. And finally, the graphics, while not bad, do not resemble next-gen gaming.
This game is decent if you like the genre but may not even be worth a rent if you don't. I did bring up a lot of negative points, but truthfully they can be overlooked for the giant battle scenes where it is actually somewhat difficult... or the giant battle scenes where it's just you, your big sword, and 10,000 helpless goblins standing in line to die.
