The one that springs to mind is Killzone.
I had seen some very mediocre reviews for it, so I was scared off. But when I saw the glowing reviews Killzone 2 was getting, I knew I would need to play the first game before moving on to the second. So I rented it from GameFly (back when I had a GameFly account). And I loved it. Another reason not to put too much stock in aggregate scores :)
