Mind-bogglingly bad, back-breakingly funny.
1 October 2001 | by shivermetimbers15See all my reviews

Where to begin? The soap-bubble thin plot? The lame "hero"? The annoying little kids? The repetitive and strafing footage filled battles? I honestly don't know. This film fails on so many levels, you can't really pinpoint what makes it the horror that it is. I don't think Mike and the Bots were even able to cover half the bad points that occured in the movie. The plot in the movie seems to continuosly go around in circles, with the evil bulletheaded aliens appearing, the scientists trying to look worried, the children in hot pants running, and Space Chief coming to the rescue. Sometimes we can't be sure exactly what is going on; all we know is that it's bad. So it comes to the final "climactic" battle, blah blah, the bad guys are defeated after a lengthy missile sequence, yadda yadda, and you're just glad it's over.
