Those reviews which point out the absurdities in this story are likely right. The characters are about as thick a sheet of newsprint, the plotline often suspends belief and the acting frequently trends towards the sound of an American football hitting one of the uprights.
However, if you're an action fan (I am), you will find it pleasurably entertaining to look beyond all of the above and just enjoy a film of the genre that rarely rests for expositional development - character, or otherwise. Campbell's foot is on the gas start to finish and that pleased me. I would agree the final result is fairly wooden, but less than an IMDB 5? Not in this reviewer's opinion. Relax everyone, not every movie these days aspires to 'rosebud' status. That's why you smuggled your own snacks into the theatre, right? Eat, watch and be entertained. Still not sure? Make it a matinee showing and you are likely to agree not only with this review but the price of admission as well.
