If GTA4 isn't a 10/10 game, why did it get reviews like it did?

I thought it was a pretty good game, but no 10, and I felt past GTAs were better.  I'd give it an 8.5-8.8.

Sometimes I do come off as a bit anti-GTA I suppose, mainly because the people that claim anybody that doesn't think it's a 10 is just a hater annoy the hell out of me.
