As for reviews of MJ experience they are all over the place. Amazon has the Kinect version the lowest rating of the 3, but the PS3 version is best reviewed, actually just checked, Wii and PS3 version rated the same 4 and a half stars
Meta has the PS3 as the highest rated one, with a 66, 360 with a 61 and Wii with a 56. Make of that how you will, but none of those scores are anything to be proud
