This is not a bad second feature on a movie bill. The powers that be have given the potential viewer that option by putting it in collections with as many as 8 or 9 other B pictures. As such, weighing in at only 76 minutes, it is a nice filler when you have a little time to kill and don't want to get involved with a longer, more engaging film. That's the way I used it, and as such, it served the purpose pretty well. Yes, as reviewers point out, there is a bit of cocamamie business at the beginning which is irrelevant to the rest of the film, something about a prison area and the need of passports. Forget it, except for a sequence at the very end, it plays no role at all to which you need attend. True also, 95% of the action is in a limited area which seems fully equipped with endless corridors, dungeons and assorted hiding places. To me this simply meant that the whole film was really only what would be a segment of a longer movie. Why worry. Yes, I, too, noticed that the X-man was capable of extraordinary killing power against presumably trained policemen, some of whom wore protective gear, others of whom wore none, with no apparent ill-effects. One can point out other elements which can contribute to a moment's bemusement; however, the point is, that by accepting these without quibble, over-all it is a not bad way to fill 76 minutes. There is action, there are untenable situations from which to escape, there is a lot of shooting, and a woman comes out top-dog.
In sum, if this is not going to be THE event of your evening, if it is just a filler, as most of TV fare is, then it is worth the few cents it costs if purchased as part of a collection. I would not ,and did not, buy it with a four dollar (plus purchase price) bill to get it, from Amazon.
