All I can say is... well, look at the source.
Kind of reminds me of the outlet that gave Demon Souls a super low review.
CrapReviewSiteX:" I have an idea, lets review a game poorly because we are poor at the game"
Seems all too prevalent among startup review sites.
EDIT: Ok, went and read whole review. My above comment stands. This is not even a review of the retail game either, just the beta... in a phase of beta where people in general were still figuring out what to do. Actually there are so many flaws in the review, I would not know where to start in addressing them. But the reviewer essentially said that " This game isnt MW2, and I did not know what to do ". He also co,plained about people not working together. In my beta experience, many times there was some degree of cohesion and teamwork even if not intricatly planned teamwork... this tells me he limited his playtest of the beta to one or two matches.
