Ticking Clock

I just want to be entertained and i'm easy to please. I don't even see most of the flaws in a movie reviewers will typically mention. But only a few minutes into this and I was asking - can I stand to watch a movie where the main character is so unbelievably stupid? Can anyone act against their own self0interest so consistently? For that matter can the police really be as stupid and sloppy as this about what he tells them? Fortunately this settles down some after a bit, but it's actually the number one problem I have here. Otherwise I liked it. Could have done without the excessive clues to the "twist" ending though. It's not not the sort of twist one expects in a crime film so it could have been played for a major, "whaaaaa?" effect, but they tossed that chance away.
