Senses of Cinema says, "Martin remains an artistic success in terms of its effective explication of the director’s strong thematic interests as originated in Night of the Living Dead". DVD Talk calls it "one of the single greatest vampire movies of all time".
HorrorNews.net says it "it lives up to its ambitions in long sequences, if not throughout the film, and there are many pleasures in both the visual treatment and the often witty script." Classic-Horror.com says, "Romero demonstrates, without a doubt, that the terror of vampirism is not in the myth. According to Romero, there is no magic, and that reality is far more terrifying than any creature of the night."
