I kept having to double-check whether the IMDb rating I was seeing was for the right movie.
This movie is good. It doesn't even look low-budget, if you ask me. The production values, the sets, the props and effects, and even the acting are all pretty well up there in quality and are actually above-par for an indie flick. In fact, the only clue I can see for this even being an independent film is the lack of celebrity actors. Plop a couple famous faces in here and I think anyone would be hard-pressed to tell the difference from a Hollywood production.
The only explanation I can see for the poor ratings is that people were expecting a sci-fi flick and are judging the movie's compliance with that expectation. I've seen this phenomenon before, and it's sad, because good movies end up without the recognition they deserve.
This is actually a good movie, in nearly every way. It's basically a war movie with a touch of sci-fi, and in that regard it's actually rather exceptional. It's well-written and well-acted, with convincing combat, and an interesting and original story. It's my hope that people disregard the low ratings and give movies like this a shot anyway.
