From my 1950s Science Fiction Marathon, part 7 of 12.
Invasion of the Body Snatchers, 1956. Plants from space are replacing people.
Directed by Don Siegel. Written by Daniel Mainwaring, based on a book by Jack Finney. Starring Kevin McCarthy & Dana Wynter.
Concept: 3/4 (Good)
Story: 2/4 (Indifferent). The best thing about the book is the ending, and yet they felt the need to mess it up in both movie versions. In the 70s, they gave it a mindless zombie movie ending. But in this version, they don't even bother to replace it with anything. There's just... no ending. The last 20 minutes of the movie is nothing but flailing gibberish.
Characters: 2/4 (Indifferent)
Dialog: 1/4 (Bad)
Pacing: 2/4 (Indifferent)
Cinematography: 3/4 (Good)
Special effects/design: 3/4 (Good)
Acting: 3/4 (Good)
Music: 2/4 (Indifferent)
Subjective Rating: 6/10 (Okay, 2/4). Maybe I would have liked it if I hadn't read the book. I can't tell. During the time when suspense might (or might not) have been building, the adaptation is so close to the book that I couldn't really separate the two.
Objective Rating (Average): 2.3/4 (Okay)
