Well, I rented this game today, and despite the bad reviews, the this actually an amazing game!
The gameplay is similar to Diablo, literally. Using the nunchuck:
You move with the control stick, shield with the "Z" button and I forget what c does...(I think iy picks up items)
Wiimote: You use the arrow keys to do various things like heal and shit, but the way you control is like an action rpg on the pc.
You look with moving the wiimote..and you shoot with "B" and do something with "A"?
Zoom and and out with 1 & 2, (why not + & -?) and + opens the menu (save, load, quit, etc...) and - opens your inventory.
So, it's an action rpg.
How? Easy, think Scurge: Hive, that underrated game for the GBA.
There are a few classes, flame thrower is one, seal, sharp shooter, bomb expert, some melee class, and...maybe two more.
The monsters come fast, and don't stop coming.
Graphics: 8/10 (There are better graphics on the wii, but this is pretty good)
Sound: 6/10 (No casltevania)
Gameplay: 9/10
Value: Worth it, it'll keep you goin' till Metroid Prime 3 comes out.
I truly think this game is legendary. Get it, it's really worth your time.
All and all, it does what it's supposed to do, it delivers what the genre promised, and it does it well.
