Easy to watch as there is little in the way of story, so good for a night where you want something on in the background.
What little works in this film and there isn't that much, is ruined by poorly choreographed fight scenes where it is nearly impossible to see what is happening. On top of this there is a whole cast of highly underdeveloped and unlikable characters, it feels like a poor man's sci-fi remake of Red Dawn.
My main issue is why the aliens expended so much effort to occupy such a small town and at the started opened fire on a football match...
