I prefer to think of Midsommar as carefully paced than slow. It's a transformational film ("folk horror" is a nice fit that way) and very, very well-acted. It sticks with you, I think a bit more than Prometheus. Then again, my favorite among the group is Spider-verse...
I like your "carefully paced" distinction. I agree, and retract my "slow" notation. I really do like the "folk horror" designation the more I become familiar with the term. It really fits. And yes, it really sticks with you long after it ends.
It's a film that can be viewed at least two ways.

Most people initially think of Christian as a bad guy and deserving of his fate but is he really? Is Dani a highly manipulative person clinging forcefully to a relationship she knows is dead for selfish reasons with no regard for Christian and dooming him as soon as she has another support system, another family? Dani's smile at the end is terrifying. Extra points for the bloody eagle, always wanted to see one of those in a movie since first reading about them in Hannibal.
Have you watched Vikings? There is a very detailed scene with one being performed.
