Manhunt - No.
I have played Metroid Prime 3 and Resident Evil 4 (though I played RE4 on my PS2, not on the Wii). I can definitely recommend RE4. MP3, on the other hand, I didn't like so much. The whole game seemed totally lifeless. Visually impressive, with a good control scheme and fun abilities, but I just got bored with it.
Other than those two, I haven't played any, but they have all gotten good reviews (other than Manhunt). Then again, MP3 did too, and I didn't like it.
