One word: UNIQUE The casting alone would make this movie worth 10/10: Johnny Eck (no legs), Randion the living torso (no legs/arms), Josephine Joseph (hermaphrodite), midgets, pinheads, siameses twins, a bearded lady, an armless woman, a skeleton man ...
The plot: In a circus, a woman wants to marry a midget for his money, and kill him, with the aid of her lover. But the other freaks will discover it, and her evil plans will be changed. Yes, this plot appears limited, but the circus was a good argument for Tod Browning to show all the freaks he had gathered. He wanted here to make a more shocking movie than his previous ("Dracula"). He managed, but maybe a little too much, because "Freaks" was a burden for his future in Hollywood.
The other idea behind this movie is that freaks are people like everybody else (at least in their heads) and therefore should be treated as everybody else. In fact, we should try to forget these differences. Obviously true, but everyone knows that. So why make a movie like this (and watch it)? As sad as it sounds, it's because we 'like' to see freaks, to see these people different. J. Eck declared about the movie shot: "It was wonderful, for the first time of my life, I felt normal". The other freaks were not looking at his handicap (what people do ), but at him, the individual. This quote highlights 'our real nature'.
To be honest, the non-freaks actors are really playing badly. In fact, worst than the freaks, whose this was for most of them their only movie of their life(!). The dialogues are sometimes hard to understand, because the sound was badly recorded (remember it was in the early '30s), and it's in black&white, but don't miss it!!! There are truelly scenes you will remember all your life (the wedding banquet, Randion lighting his cigarette with his mouth ...). This movie is as its casting: unique! And I think Tod Browning has found the right tone to treat this unusual subject. My only regret is that "Freaks" is a bit too short (1 hour).
10/10
PS: In the imdb, is mentioned an other version, a recent one, "Freaks uncensored". I've been looking for it, but it doesn't seem to really exist (and there is no user comments!). So if anybody knows...
