as a FPS it's totally mediocre (meaning it's still decent, but there are so many better FPS out there that's it's simply not worth it)
It's extremely short. I know MW2 was really short as well, but it had at least an extra mode with new missions that could be completed alone or in co-op, which also lasts for some more hours.
Graphics are rather weak. bad textures, mediocre character models. Rest is okay.
Level design is bad. Play the first 3 minutes of a level and you know what the rest looks like. Also you always need to wait for your AI teammates to open doors or give you the order to kick in doors. Obstacles where it's impossible to jump over unless your team finally allow you to do it. I'm also not exactly sure how many weapons are in the campaign, but I'd find it hard to believe if it was more than 10. Also if (huge if) you're able to run ahead at one point, you will be surrounded by directly in front of you spawning enemies.
It's buggy. In my 4 hours playthrough I encountered 2 game breaking bugs where my AI teammate didn't open the door to the next part of the level or didn't help me up a ledge. For a 4 hours game, that's too much.
Story is bland, cinematics are boring. You have absolutely no connection to your team, because 1. it's so short. 2. You play as 3 different characters in 10 missions and each of your main characters has a different team. Most missions are simply boring.
Gameplay wise it's okay, but I've seen better. Aiming can be off a couple of times, making a headshot difficult even though you put your red dot sight exactly on a head (on medium range). The driving parts in the game are a joke. They have no purpose and it's not even fun because you won't encounter any enemies. It also tries to copy the controls from CoD there, but IMO driving in CoD is still wuite a bit better.
AI is okay-ish. They do kill some enemies, but sometimes they let some of them run past right past them, which is annoying when you're trying to back him up.

Even though I'm a big fan of FPS, I just can't give this game a great score. Hard to believe, but Black Ops will smash this game and I'm not even talking about the sales. I also think PS3 owners will have much more fun with the included MoH Frontlines HD.
To describe the game with one word: forgettable
