Assassin's Creed is beautiful to look at, and great fun in places, but also very repetitive. It's essentially a testbed for the crowd-interaction stuff planned for Splinter Cell Conviction, rather than a game of it's own.
Personally I think if you could graft the first-person view from Mirror's Edge (which feels even more like a technical demo) onto the combat system and jumping-down-into-fights thing from AC, you'd have the perfect Batman game...
Thanks


Still fancy giving it a whirl though
