Well, I had to tell someone that this is a great sci-fi movie, and y'all are it.
If you don't like sci-fi or shoot-em-ups, move on. If you do, this could be subtitled "Eye Candy and some Brain Food". This relatively low budget South African film is a sleeper hit that doesn't look low budget in the least, and is a little different than the usual fare.
The first third or so establishes the basic premise. A giant ship parks over Johannesburg, but nothing happens. Finally humans cut their way into the ship and find tens of thousands of starving animalistic aliens. They resettle them on earth as a humanitarian gesture, and clashes with humans begin. This section of the movie is rife with apartheid parallels and ironies, especially the reactions of the former victims to the new arrivals.
Then things pick up...
It could have descended into a morality play, but instead things go awry and we move into a very engaging action flick as our hero (a human corporate goof who is tasked with relocating the aliens) begins to change sides, literally.
There is the stock evil corporation seeking to exploit alien technology, and another standard type in the racist brutal mercenary, hired as security for the relocation. I won't post any spoilers, but you don't think stock evil types would go unpunished, do you?
Stuff happens and caps start a-poppin', and it would be safe to say that Someone gets their hands (well, not exactly hands)on some extraterrestrial hardware with fairly spectacular results.
The director is a fan of the handheld shakey cam, but fortunately not to the "Blair Witch" extent (which I thought was a stupid movie with stupid photography). It works pretty well where it is used in this urban warfare environment. The Big Special Effects are extremely well done.
This movie is thoughtful enough to stay with you after you leave, but shootey and suspenseful enough to keep you interested while you're there. I will confess that I liked Starship Troopers enough to buy it, and this movie is waaay better than Starship Troopers. This is the best sci-fi I have seen this year. I did not recognize any airguns among the alien weaponry but I think some of the stock designs would appeal to the Russian goth types.
