The score has been all over the map. Some say the game is broken, others say it's a lot of fun. IGN gave it a 7.5, Joystiq gave it a 1/5 (complaining mainly about how they disliked Kinect), G4 gave it a 3/5 (citing controller recognition snags as what bumped it from 4 to a 3, though they did say "Granted, that was about 20% of the time, and the other 80% were spent in pure enjoyment.")
What I'm curious about is how Kinect's ability to learn translates to games. CVG wrote a in depth review detailing the calibration process:

Guess all I can do is speculate until I try it myself.
