I gave the game lots of love when it was released. But the game is like junk food, empty calories and no nutritional value. That's okay but it doesn't take long before you just want a real meal.
The incredibly repetitive nature of the game and the lack of any real story-telling just makes a short lived and disposable experience.
I had fun, I played through a couple times, and the game looks great. I certainly got my money's worth ($30), but there is no desire to come back until they give us something that actually has some meat on the bone.
I think mixing up the gameplay a bit, adding more boss fights, and having some actual story telling could have made this a far better and more complete experience.
