"Cinematographer turned director Freddie Francis was already an old hand at Amicus, having already helmed Dr. Terror and two non-anthology films... Though not his strongest film, this one is a solid example of his style with its vivid colors, nicely burnished cinematography, and swift, efficient storytelling that ensures the audience won't get bogged down in one story for too long. The framing device is a great opportunity for Meredith ham it up like nobody's business, and though the ending comes off as more than a little muddled, at least it avoids the usual cliché of revealing that everyone was dead the whole time. Perhaps most significantly, this was one of five Amicus films written by Robert Bloch, a very in-demand writer in the '60s after the mammoth success of Alfred Hitchcock's adaptation of his novel, Psycho." - Nathaniel Thompson, Mondo Digital
