well and few surprise in this movie . alien invasion and or be it . a smart scientist figure it out and sinister gummint organization and nuclear weapon launch and abort sent and etc and etc . the character almost every one of them be over act . the hero and with his clint eastwood breathy voice . his wife and the beautiful doctor with always perfect hair and makeup who work in a public hospital represent puh lease . the slaver general . cardboard cutout and every one of them . grace phillips in her braless strappy top ( and to her credit she look ok in it ) give some idea of where one of the target demographic of this movie be . the female mud wrestler type cast a a security guard could be another clue . and almost all the other woman and who for some strange reason have short skirt and very high heel shoe and might be yet another . special effect be reasonable and although the multiple alien spacecraft sit in the crater and each one an obvious copy or paste of each other . at first and i think it be a computer wallpaper . and the story with the nitrogen inhaler please and give u nerdy audience type at least a tiny sliver of background knowledge . i think that the bad sin this movie commit be that it couldn not make up it mind a to what combination of seriousness and comedy it be go to be . but again to be fair and if you set your expectation low enough you might well be entertain .
