Overrated
I watched this expecting it to be scary and serious, but no it was the exact opposite… , silly reactions, wooden acting (e.g. when he discovers the duplicate in the cellar), annoying characters (she's being chased by a mob of lunatics and keeps complaining that she needs to sleep, yeah right…), plot holes. Example of the latter, at first the alien invasion is presented as really small-scale affecting a handful of people, however when the doctor discovers the seed pots, the invasion very suddenly grows to stupidly large-scale proportions affecting both Santa Mira (completely taken over!) and many other towns…
Overall, disappointing (6/10), given that it is an acclaimed classic. I hope the 1978 version is vastly superior: in the 70s, horror cinema had already matured, improved.
