I loved this film, but my friends beg to differ. It's an apocalyptic sci-fi movie from the early 80's that's far better than you'd have any right to expect. The premise is silly, of course — sort of a mashup of The Day of the Triffids with The Andromeda Strain — but the execution is actually quite skilled, with just enough self-awareness to make it fun without being a parody or dead-serious deconstruction. The setup portion of the movie is a bit slow, but it picks up before you suffer boredom. There's a point where the movie drops a new set of characters into the story, and it seems that the movie is failing to properly sketch the personality and motivations of one of them... but it turns out there's a good reason why you just have to wait for the explanation. Score: 4 stars out of 4, although your mileage may vary.
