the plot line be so simply you will swear you have see it before . people wake up to find that their city have be evacuate and be under siege by alien robot thingees ( of which we never actually see more than one on screen at any give time . ) while survivor try to keep one step ahead of the monster and the army be bravely try to figure out how to defeat them . can not say the movie be all that great . it be clearly do on a budget and with character talk about what be go on rather than show u thing go on . ( something a modern film would never do . ) the acting be fairly decent and but the threat just wasn not all that impressive .
