Sci-fi horror from the 1950's is so much fun, but the actual script writing usually leaves a lot to be desired. Not so for Them!, which has all the fun of the best of 50's creature-features twinned with a very intelligent plot. The dialogue is quality, despite its heavily expositional bent, and there's just enough interest to the characters to keep us invested.
The parallels with Aliens really struck me - I can almost imagine the pitch for that movie being "The sequel is going to be like Alien meets Them!" - especially the final act when our intrepid heroes venture down into the nest!
Loads of fun, but anything but mindless, this one.
