The screenplay was written by morons for morons. If swearing excites you then you may well enjoy it, but for normal people it is tedious. The characterizations were pathetic, but the underlying theme had great potential, A great shame that it was not given to a better team.
Unfortunately Chuck Norris does not have the same charisma as Bruce Willis, Stallone and the other go it alone action heroes. The plot was good, but the film could have been much better with the right actors.
You need to have a reasonably high IQ and some IT knowledge fully to appreciate this film. However, it could have been improved with more detailed explanation of the premise. There are also too many loose ends - what happened to the other hostages? Why was Hugh Jackman allowed to live? Why didn't he tell the authorities about the real "Travolta" ?
