The SP is shit turds with one or two nice spots.
Pretty much. The single player experience failed to bring anything new to the table and simply felt dated next to so many other shooters this fall. Every shooter I've played this fall has been a blast with this standing as the lone exception. Perhaps I was naive for expecting something different from Call of Duty 2 (which didn't really interest me either). The design of these scripted shooters really just doesn't work for me any more. It was exciting back in the days of MOHAA on the PC, but times have changed.
Furthermore, the timing was pretty bad. The following two weeks saw the release of games such as Mario Galaxy, Uncharted, Mass Effect, and Assassin's Creed (all four of which are far more entertaining than CoD4).
