De IGN:
6.5 Gameplay
Solid rhythm gameplay marred by poorly-implemented controls. Casual gamers probably won't notice, but the hardcore won't be fooled.
Here in the IGN office, fans of the original Samba pick up the remotes, crank up the difficulty, and find the controls to be almost unworkable.
On the Dreamcast the maraca peripheral was height sensitive and did a much better job of reading your movements. This Wii version puts all its hopes on the remote's accelerometer and it turns out it's not up to the job.
Lamentable...
