Will this be a series? *Spoilers*!!
I am usually quite forgiving with low budget sci-fi but this movie deserves a 5/10. 6/10 at best. If this is supposed to be a pilot for a series then fine, it was ok and the series might actually have some potential, but as a stand alone movie it was pretty weak.
1. Acting and script is not exactly top-notch and pretty predictable. The characters are cliched to a point of annoyance.
2. Just deviating from plan and not killing the target and thereby risking the one chance to save 9M People and the whole future is borderline crazy. As is sending 3 amateurs to do the job in the first place instead of a trained hit squad that would stick to the mission.
3. Upon return everyone in the bunker knows exactly what is going on as if nothing has changed but the rest of the world doesn't. This was so blatantly odd that it really bothered me (and I am generally not someone searching for, and bothered by "plot holes".
4. The "genius" playstation geek that can simulate the whole world in 3 seconds by the click of a mouse is so far fetched that it's comical.
5. The time portal thingy jumping to the perfect time and place in history just in the same second that it is needed is such convenient writing that it is annoying. As is getting back into it virtually in the last second before it closes.
But most of all...
6. After spending minutes explaining, at the beginning, that the wormhole or whatever it is, jumps around at random without anyone knowing to when and where, the evil dude at the end knew exactly to put on his cozy snowcoat because he just knew that it would take him into some snowy woods. And exactly at the right time for him to initiate his evil master plan. Not maybe, say, into the ice age before civilisation exists, where he would be screwed.
All I can say is "facepalm".
But as far as the special effects, it was passable so if this becomes a series, it might be a worthwhile half and hour Friday night watch. It's almost like a Stargate reboot.
