heroine is a doubtful mix of immature emotions and steely resolve, as shown in one poorly handled scene when Candy underreacts to the death of her beloved dog." However, he goes on to write, "The film's good reputation comes from fans that admire the killer's technically elaborate murder scheme, and ace Hammer cameraman Jack Asher's arresting camerawork. A final surprise lifted from The Third Man could have provided a perfect shock finish, but the movie goes on a bit longer, clearly to tie up some moral loose ends for the censors." John M. Miller, writing for Turner Classic Movies, was more positive: "The Snorkel'' opens with one of the more memorable pre-credits sequences to be found in a thriller...While not a classic, this clever and twisted thriller, as well as Peter van Eyck's chilling performance, is overdue for greater exposure."
