The lights are on
I am one of the few who liked it. Is it the best game ever? No, not by a long shot, but it is a fun, mindless shooter, and if you play co-op with a human friend, it's better. I think the 6.5 review is a bit harsh, I would rate it at a 7.5...
I'm also one of the few who liked it, but I think that Army of Two: The 40th Day is one of the most exciteing and different styled Third person Shooter i've ever played.
My rateing is 8.5.
I just recently played it and I agree with you! I found it quite enjoyable and playing with a friend makes a tremendous difference.
