I'm quite a fan of Mirror's Edge, even with some minor errors in collision detection. Though it was an extremely nice move by EA to keep the game FPS, I wouldn't particularly say it will revolutionize the view, but it does have the sharpest execution to date.
A bit more multi-player would be nice, at least something other than time trials. Like when I first saw that there was going to be online support, I was envisioning droves of people flying across rooftops above the New Eden streets. Be it a free roam, or even having PvP races as opposed to the rather limited time trials/speed runs, the online experience was really lacking.
My only hope is that they add these elements in the sequel, and possibly polish up some of the physics in the mean time.
