Having just watched that awesome movie, and read the books, I can say that I was excited for this game. Its a love letter to the old school beatem ups like River City Ransom for one. Right now its out for the PS3 but it will make its way to the 360. I am not sure about online co-op but it does have co-op. I will do some research on that today. It certainly is worth the buy in my opinion.
