Beware. If you watch this with the sound turned off, or chance upon particular scenes without having seen those that came before or after them, you would be forgiven for thinking you'd watched a truly terrifying film. But fear not, despite the gobsmackingly shameful rip-offery, the in your face product placement (Coca Cola, Skittles, a dance number in a McDonalds) and yes, those truly creepy martians (the parents, mainly), this is actually quite a sweet and innocent film. And also very funny when it shouldn't be (the wheelchair cliff scene). A trash classic.
