Spector decided to make his masterpiece on the most limited platform with tacked-on motion controls and ended up with a mediocre game. I'll grant you that it might have just been him screwing up, but looking at the concept art, I get the idea that the vision and the end result parted ways somewhere along the development process.
I'm sure Levine is a nice guy in person and there are certainly much worse "star developers" out there, but the reluctant "apology" about motion control pretty much sealed the deal for me. It's obviously my fault if I expect more from the guy who made System Shock 2 and Freedom Force, but that's how I feel.
I have long ago abandoned buying games based solely on their genre or the developer, there are just too many good games out there for that.
