Not a bad concept and I have little doubt that this looked a lot better on paper than the final product, which is kind of a mess. I spent close to half the movie getting a clear picture of what the heck I was supposed to be watching with a poorly constructed, convoluted preface combining two different stories that would have made Godfrey Ho proud. Once you get past that, you are watching somewhat lack-luster action with a nonsensical romance that, not only shouldn't be happening in the first place, but wavers on this crazy, bipolar jag of the two main characters getting all mushy with each other one minute and then trying to kill each other in the next scene. At any rate, I'm pretty sure there is a more straight-forward way to show a guy is 350 years old and immortal than how these guys chose to roll it out.
The film is not quite the bottom of the barrel but getting there and not really so-bad-it's-good, either, but I'm kind of a masochist when it comes to bad action flicks, so I'm giving it four. Overall, this is kind of a boring flick and, as a side note, the female protagonist is in another, even more craptacular and boring flick called "The Lost Platoon", that could also suffice as a sleep aid if your doctor won't give you a prescription for the real thing.
