People compare this to Die Hard. For me, it's Air Force One without the plane. Same cliched characters, same nauseating American jingoistic schmaltz, same rather silly story about utterly ridiculous ransom demands being considered and even met, and a WAY HIGHER body count, it makes a good Arnie film look like a tea party. My goodness this film is violent. Bodies falling all over the place, and some rather disturbingly vicious violence in places.
The CGI is pretty dodgy in places too, frankly the kind of quality that might have been acceptable 20 years ago, but not now.
But the action is pretty constant, and keeps you engaged, and there's nothing like seeing baddies get what's coming. Not bad.
