If you believe the box, this film is about a group of young American soldiers who use a video game simulator to have a little fun before encountering a ghost in the machine, quite literally. Of course, if you are paying attention, you'll quickly notice the soldiers speak with accents and drive on the wrong side of the road. As the film is an Irish one, I suspect the cadets are meant to be Irish, not American. Beyond that, it's about right.
I watched this one with two associates and cheap vodka filtered to make it taste better, though I am not a fan of vodka. The primarily chick was mildly attractive, which I appreciate, but beyond that I think we should look at the words of the critics (besides myself). Here's three samples: "If you have seen Doom, Stay Alive, Death Row, Gamer, etc., etc., ad nauseam, you have seen Ghost Machine. There are some cringe-inducing moments of violence, I'll give it that. And Rachel Taylor makes the movie watchable for awhile, but even she can't save it from the murky camera work, hackneyed storyline, and gawdawful CGI." ... "The horror elements are not that scary and the sci-fi is not that convincing." ... "This is hands down, one of the worst movies I've seen in recent history... The most enjoyment I got out of this movie was when the screen went black and the credits finally rolled." Well, they said it better than I could. Rachael Taylor good, CGI and plot bad.
If you feel the need to rent this one, be sure to be plenty drunk or something, because it probably won't hold your attention. I find that it picks up after a while, but we are given many parts where it drops down again and no reason to care about the characters... whose names I already forgot, though I think the guy who looks like Tom Cruise is named Tom.
