I think this is probably a good example of a "product of its time", but the controversy lies more behind the idea of the horrors that "cloning" could potentially bring to the world. It all starts with the film opening with a credit sequence, taking you through what "happened" since the cloning of the sheep, Dolly (a real-life occurrence that no doubt inspired this movie). It then brings us to "the near future... sooner than you think". So, almost instantly, we get a hint of "preachy" with this one.
Cloning has become a sort of regular, everyday thing for people. Animals can be cloned, which can lead to plenty of food, but also, playing God and cloning your dying pets. Organs can be cloned for easy transplant surgeries, but so can entire human beings. Thus, the "6th Day Law" was put into place, where human beings are basically the only thing people aren't allowed to clone. Well, as any pot smoker will tell you, there are ways around laws... even if cloning a human isn't as simple as just finding a good hiding place.
We are soon introduced to charter pilot Adam Gibson (Arnold Schwarzenegger) and his partner, Hank Morgan (Michael Rapaport). They are hired by billionaire Michael Drucker (Tony Goldwyn), who owns cloning corporation, "Replacement Technologies". The pilots are made to take blood and eye tests in order to prove they are good to fly. Eventually this all leads to the actual ski trip where something violent goes down, but Adam does manage to make it back home, only to see a clone of himself hanging out with his family (along with a horrendous doll that would give Chucky nightmares).
Here, we learn that the dangerous thing about having a clone is having people try to kill you, as there should only be one of you. The other thing is, the idea of a clone retaining all of your own memories, so you start to question your own reality. Before he knows it, Adam is on the run from Replacement Tech. Security agents Marshall (Michael Rooker), Elsworth (Sarah Wynter), Vincent (Terry Crews) and Wiley (Rodney Rowland) as he tries to figure out what in the hell happened to his life. All in all, it's an okay movie for Schwarzenegger fans, but I personally consider it a sort of "nail in the coffin" for Schwarzenegger's prime.
While one can appreciate a lot of the fun clichés we have come to expect from an Arnie flick, there's quite a bit here that overshadows all of that, and in a kind of negative way. First, it just seems like a clear project meant as a message to forewarn the world of the dangers of cloning. Nowadays (22 years later) all of that seems sort of irrelevant. Is cloning real? Sure. But we don't seem altogether worried about making full clones of ourselves as opposed to cloning things we really need for ourselves. I should also point out that I'm no scientist, and have no idea what the limits of cloning are, as it's surprisingly not a whole matter I've paid much attention to. I'm still sitting here thinking "duplicator tech from 'Star Trek' would be neat.
Now that I've probably made myself out to sound not so bright about sciencey stuff, let's get to my final word on the film itself. I think that the film is perfectly passable IF you watch it as a product of its time as opposed to a present-day thriller. You might look at it a lot like someone like me would look at an 80s movie these days - you kind of need to watch it through special lenses in order to enjoy it. I'll also point out that there are MUCH better Schwarzenegger titles out there, if you're on the lookout for that classic Arnie action. My personal favourite is still 'True Lies', but his library is a lot of fun to go through if one is looking to have a good time. This is just on the lower end of it.
