For once you can believe the box-cover.

Rating: 9/10 (26 November 2010)

This movie was everything it's case said it would be: 'an explosive, action-packed hit with incredible fight sequences', 'a super-charged thrill-a-minute spectacular loaded with non-stop action'. These are words you seem to find on just about every movie-case these days but in this case, you can believe them. It had me fully enthralled from start to finish. The tempo seemed to ebb and flow from full-out action to dramatic character interaction and development flawlessly. The car-chase and hand-to-hand fighting scenes might be the best ever put to film and Matt Damon, who has sounded like he's trying a little too hard in some of his other efforts, is 100% believable. Everything about this movie draws you in and forces you to want more.
I'm not sure why it's only a 7.7 in the eyes of the IMDb world but in my opinion, it's worth much more. Easily a 9. This is what action movies should aspire to.
But that's just my two scents. ;)
