Invasion of the Body Snatchers (IOTBS) is a well-paced and highly creepy sci-fi thriller which has not really aged since it's initial release back in 1978.
This was perhaps not the best year to release a movie entitled 'Invasion of the Body Snatchers'. Star Wars was still filling the cinemas a year after its release, and the big-budget remake of Superman was released at around the same time, while IOTBS was initially perceived as another shaky 1950's remake.
However, IOTBS is a genunely edgy, frightening film that has been critically under-rated for many years. The lead performances from Sutherland, Adams, Goldblum, Cartwright and Nimoy are excellent, and we have genuine sympathy for each of the characters involved as the unseen, parasitical alien forces close-in on them one by one. You will not 'sleep' easily after seeing this, so to speak.
Director Kaufmann accurately portrays an unsettling undercurrent of 1970's urban paranoia in the setting of San Francisco, and almost parodies the needless psychotherapy undertaken by millions of American's during this period, in a country not completely at ease with itself in the first place.
There is little in way of gore, although what shocks do occur are effectively dealt with,with creepy camera angles which shows a weak society slowly and unconsciously surrendering to superior extraterrestrial forces, which manifest themselves in an unlikely yet frighteningly realistic manner. The depressing, final scene with Veronica Cartwright and Donald Sutherland is one of the most haunting endings of all time. Overall, this comes highly recommended.
