It's one of those films that I seem to appreciate more each time I view it, like extra detail that I missed.
I will be rewatching it again soon as missus wants to see it after I showed her Ari Asters other horror, Midsommar the other day, a film i've now seen 3 times and enjoy more each time. As you mentioned for Hereditary, mountains of detail that becomes apparent on a rewatch.
