I don't see how it's ”praising satan”. A lot of horror films deal with the supernatural and evil forces. Unless it's a really dumb movie, that stuff is usually intended as a metaphor, like in Hereditary it's for mental illness. It's a great film, gripping and unnerving as hell. The mother's descent into darkness is brutal.
Ari Aster's follow up 'midsommar' is worth checking out too. It's slower paced but fascinating. There's not a lot of supernatural stuff in that one.
