Finally saw this last night and loved every minute of it. Edgar Wright continues to prove that he is a master at his craft. However, I must admit that I am a bit biased because Wright has been my favorite director for like 15 years now lol...
Edit: Having said that, as far as "psychological horrors" go, it's actually only the second-best I've seen this year... best 2021 psychological horror is Saint Maud, IMO.
