8.5 from IGN.
7.7 from Gametrailers.
Jim was a bit disappointed at Destructoid and gave it a 7.0 [http://www.destructoid.com/review-saints-row-the-third-215423.phtml].
As a huge fan of the last game, I want to shout this sequel's merits from the rooftops, but while the experience is often amusing and littered with some remarkable moments, I cannot help but feel a little let down by the final product. It's still a good game at its core, but it's not a patch on its predecessor, as it seems to have forgotten about Saints Row 2's achievements in its blinkered pursuit of extremity. It took me over two weeks to beat Saints Row 2, and I still wanted to stay in Stilwater. I concluded Saints Row: The Third in less than two days and feel no compulsion to return to Steelport anytime soon.
He even said he thinks they might have kept the experience short to help them sell the planned DLC.
From what I've read/seen, I actually think I'll buy Saints Row 2 sometime in the nearish future rather than this. The price difference and the quality comparison makes it seem like a better deal.
