I feel like Hereditary is an adequate horror, ticks all the boxes but the end product never really resonated with me, Midsommar on the other hand I absolutely love and think it's fantastic - having watched it 3 times already.I really enjoyed it, too, though I think I liked it even more during the second viewing. It's one, like Midsommer, that you will probably notice more details each time you revisit it.
If you haven't seen Midsommer, then please do!
As you say, Midsommar reveals more and more like an onion on repeat viewings.
