tycus be almost as bad a a science fiction film can go . i can hardly find something good to say about this film . the premise be completely wrong . a comet be suppose to hit the moon and cause catastrophic damage to earth and but nobody believe the scientist who predict this . a whole underground city plus a launching pad for nuclear arm rocket be build in the california mountains without anybody noticing . when the comet near earth the news make it to the tv and newspaper hardly a day before the event . and so on and and so on . neither do any kind of emotion make it to the screen . be the genius who discover the comet and build the underground city a savior of humanity or a beast . the director or dennis hooper who be play the role do not seem to decide until the film be do and and actually it do not make any difference because act and directing be so confusing that you end by wonder what do this film try to say . the special effect be so cheap that not only that they can not be convince in the era of computer effect and but they could not have be convince even in the 50 and four decade before this film be make . a total waste of time .
