DVD Journal says, "Even if this is your first exposure to the German silent cinema, Dr. Mabuse dishes up a fine paperback potboiler of a story filmed with a sense of style and craft that, like Dr. Mabuse himself, is often hypnotic." DVD Talk calls it "a special treat for people who love movies". Slant Magazine gives it 3 out of 5 stars, and likes the sequel better. Rotten Tomatoes has a critics score of 92%.
