Great movie (With an interesting plot hole)

Rating: 8/10 (6 October 2006)

Great movie, no doubt about that. But wait a minute, did the Matt Damon character really believe he could "delete Costigan's existence" without Marky-Mark Wahlberg's character coming back to ream his butt? Tjis just did not make sense to me.
Spoiler warning****
The fact that Marky_Mark's character winds up wasting him in cold blood, just back up my thesis.
Usually I just see a film and go along for the ride, I can 'suspend disbelief' and all that other cool stuff. Just seemed to me this was a huge plot-hole and there were several other minor ones in the mix as well. Okay, some minor flaws in a very very good film.
