This game has it's flaws, like all the others it is not perfect but it's very fun nonetheless.
And no it's not like mw2, just because the graphics look the same it does not mean the gameplay will be the same.
In my opinion people who give bad ratings is because they played it once, got on a lobby and they got their butt kicked pretty bad, but don't hate on the game because you are bad at it. I see way less camping in this game, if you like camping and waiting two minutes to find the enemy go play battlefield 3. ( I like BF3 as well but I play COD more often )
I think this game is great like the title says and I see my self enjoying it for the rest of the year until the next one comes. And if you look around youtube at real gamers they all agree that this game is great.
The campaign was amazing and the graphics were breathtaking. The missions were fun and the story was intense and kinda of a downer.
the only problem with this game is the multiplayer. It takes awhile to find a game and its common to get kicked off due to lagging. Also i think a system needs to be in place to set matches according to rank. The day after it came out there was people already 30 plus rank and you have 1 rank players going against 70 rank players. The maps are good and plenty but theyre so maze like with a million of diffent camping spots and hardly any decent snipping spots that its just chaos
