It has an insanely boring and highly stupid 3 hour tutorial. Then once you pass that, the difficulty doesn't increase. You find yourself running around looking for things, it doesn't seem to have that much battles to balance it out, or if it does, they're insanely easy so you probably wont notice it. The game is also really long. You could say that that's a good thing, but due to the fact that it's really easy, it just feels like a really long easy game.
And the bosses, they are so mind numbingly easy it's not even funny. They don't even want to kill you it seems, and each hit takes off like half a heart.
For the first boss, you stand at the back of the room and wait until that monkey drags a bomb infront of it, then you throw your boomerang at the bomb and push it towards the boss. That's it. Apparently if you stand at the back of the room the boss can't reach you, so it doesn't even try. I learned that the first time. You shoot the red glowing thing on the second boss' head, pull it over, hit it, it stands up, you shoot the red thing straight away, pull it over, hit it, it stands up, you shoot the red thing straight away, pull it over, hit it, it dies. That's it. And I literally have no idea how the 3rd one hurts you. The 4th one is really fun, but sadly it probably wont touch you.
Anyway, the bosses look fantastic, the whole game looks fantastic. The story is different, not as epic as WW, just different. I'm not sure what everyone says about Midna being a well made character though, she's a bit of an anti-hero, then she turns nice.
But anyway as I said, the game looks fantastic, and it uses the Wiimote really well. It's a good game, but it's really easy. Instead of buying it, I think you should just get a loan from someone.
