PRO:
Excellent... The film holds attention without explicit violence or gore. -- Variety
Genuinely funny, yet it's also scary, especially for young women: it plays on their paranoid vulnerabilities. The queasy and the grisly are mixed with its entertaining hipness. Its probably more fun for women who are past their childbearing years. -- Pauline Kael, New Yorker
Ira Levin created Rosemary's Baby... But it was Polanski who endowed it with plastic elegance, visual shape, vocal timing, frightening camera movement and the full acting benefit of high definition performance... Levin is the creator and Polanski the artist. -- Kenneth Tynan, Observer
By far [Polanski's] most satisfying film so far, precisely because it is stylistically polished, restrained and pretty conventional, and because it is a glossy, superficially psychological horror thriller with no noticeable pretensions to be taken as anything more. -- John Russell Taylor, Times
Like all good horror films [it] is set in a completely realistic and tangibly normal environment. -- Sean Brestin, Irish News
Tension is sustained to a degree surpassing Alfred Hitchcock at his best. -- Daily Telegraph
The characters and the story transcend the plot. In most horror films, and indeed in most suspense films of the Alfred Hitchcock tradition, the characters are at the mercy of the plot. In this one, they emerge as human beings actually doing these things. -- Roger Ebert, Chicago Sun Times
Classic modern-day thriller by Ira Levin, perfectly realized by writer-director Roman Polanski. -- Leonard Maltin's Movie Guide
MIXED:
It may not be for the very young, and perhaps pregnant women should see it at their own risk. -- Motion Picture Herald
A pleasant surprise [is] the very real acting ability of Mia Farrow... The film's most memorable performance though is turned in by veteran Ruth Gordon... dispensing that old Black Magic she knows so well in a voice that sounds like a crow with a cold. --Time
Conspicuously well made. But it is insufferably silly. -- Dilys Powell, Sunday Times
The section of Rosemary's Baby that's been most publicly controversial - her nightmare of being raped by Satan, which the censor has unjustifiably cut - is actually its least successful... The sharpest bit of casting is Mia Farrow. Her curious physical deficiencies are turned into advantages by Polanski who makes the thin, ravaged, angular, listless, anorexia-like appearance that the character presents... into a pathetic counterpoint to the supernatural powers operating on her. -- Alexander Walker, Evening Standard
Seminal gothic melodrama which led in due course to the excesses of The Exorcist; in itself well done in a heavy-handed way, the book being much more subtle. -- Leslie Halliwell, Film Guide, 1970s
Glossy schlock about satanists and the devils child is not as scary as it is uncomfortable to watch. It becomes upsetting seeing Farrow not only look pale due to her unusual pregnancy but feel confused and constantly tormented... A big hit that is on some levels quite enjoyable - yet its really an ugly film. -- Danny Peary, Guide for the Film Fanatic, 1986
CON:
Make a film like Rosemary's Baby? I wouldn't touch it with a five-foot Pole. -- Billy Wilder
The film is very proficient, but all the same, what's it for? If it weren't made by Polanski, I suppose one mightn't ask the question. A horror film isn't for anything; it's just something to scare yourself with. The trouble is that Rosemary's Baby doesn't really scare you much. -- Penelope Gilliatt
Whoever directed this picture must have been the brilliant Polanski's dopey Doppelganger, if not indeed his Hollywood stand-in... The lone authentic bit of horror in the film is Ruth Gordon's performance: a sort of self-serving, nonstop tuneless singsong issuing from a decrepit butterfly that thinks itself the Empress Theodora, it is easily one of the most offensive spectacles of any year and does make Rosemary's Baby, whenever it is on view, perhaps not horrifying but certainly disgusting. -- John Simon, New Leader
If it lacks some of the book's suspense, put that down to a rasping performance by Ruth Gordon, who plays all parts exactly the same... As the witch on the case, she couldn't frighten a cat. -- Esquire
Ruth Gordon is the mother, giving the same eccentric performance she has been giving for many, many years, except that now, mercifully, she doesn't try to be sexy. -- Stanley Kauffmann, New Republic
