http://XNplay.co.uk finally overcame their broken Xbox and found time to review BitStream.

"superior audiovisuals"
"a nice game, with catchy sounds and visual effects and a lineup of multi-player modes"

Best bit has to be from the comments, though:

I really like a lot of things about this game, namely:
-presentation
-graphics
-music
-controls
-game mechanics
