I assume you've seen the first in the series as well? I never saw the first two in the theater. I caught the first one just this past year on tv and was hooked.
I rented the 2nd one just days before I saw the third installment at the theater. I just love the action and edge of your seat excitement.
I can't say I ever really saw anything with Matt Damon (that I can recall), but he is perfect for this role IMHO. Since it didn't seem to be running out of steam by this third film, I am hoping for yet another.
