Well, to be fair, there are only 8 reviews so far.
And to be fair, when Rise of Cobra launched, it had great Rotten Tomatoes ratings after a few days as well. So trying not to get hopes up too much, but currently, after 8 reviews, the Rotten Tomatoes rating for G.I. Joe: Retaliation is at 88% with reviews being by and large quite glowing and positive. I do fully expect this to change over the coming days, but so far out of the gate, I like what I see.
