I don't mind the review *if and only if* they didn't heavily weigh the in-game hitching problem into the rating.
I've read every Bioshock review I can find and not a single other reviewer has even mentioned any kind of slowdown or hitching. Hopefully Gamespot didn't put too much stock into a bad 360 or a bad disc. A friend of mine bought Crackdown and was furious after playing it for six hours and finding that one entire section of the city was unplayable because the game failed to load textures and glitched constantly.
After testing it in my 360 and replacing the disc, we discovered that his old CD disc had a corrupted section out of the box (the disc looked perfect). Stuff like that happens and they need to do a little trouble-shooting before knocking a game for something like that, especially after reading "after a few hours it started hitching". That sounds like a bad console to me.
