First off Harrison Ford is still capable of playing these roles, he certainly did not come off as unbelievable for the most part.
The first hour or so of the movie is top notch and plays out exactly as any good action film should, the bad guys outmaneuvering the good guy at every turn so the audience hates them even more.
Unfortunately the second half of the movie is nowhere near as strong and I believe part of this is because Paul Bettany just does not play a convincing bad ass. He's a good actor, don't get me wrong, but he's far too lenient and soft compared to similar characters from other action movies. There is a scene where Ford and family attempt an escape, only to be foiled by their captors. Following this, Bettany does respond with a nasty act, but I kept expecting him to shoot (non-fatally) one of the family members or beat them with a club or other blunt object. There were also some logic issues that bugged me, but I won't get into them here as I do not want to spoil the film for those who haven't seen it.
Despite what I mentioned above, I found the movie to be well worth the cost of admission and a fun way to spend two hours.
