Moria gives it 3 out of 5 stars and says, "Seen, Deep Red is an interesting film, although not quite the masterwork that many have called it." 1000 Misspent Hours gives it a 1-star review and says, "Against these glaring defects of both narrative cohesion and genre integrity, Deep Red has basically one thing to offer in its favor— it looks nice." Weird Wild Realm says, "I just don't find films that can mostly boast only about their good meat-cleaver scenes to be at all consequential." Slant Magazine calls it "a great horror film". DVD Talk says it "might the most beautifully shot horror film ever made" and concludes their review with this:
Not quite the fever dream that other Argento films are, Deep Red is still a totally arresting dive into the creative psyche of one of horror's true masters. In fact, it may be Argento's masterpiece. The movie's flawless visual scheme and concise editing make it a commanding experience regardless of genre considerations. Highly recommended.
