A "horror" film to which I could not buy into for a second

Just a few quick thoughts re Ari Aster's 2019 film, Midsommar, as I didn't/couldn't watch the final 30 minutes (which M kindly summarized for me), the first of which is I guess I am in no way the target audience for this film and there's no way I could possibly suspend enough disbelief to enjoy or be moved by this film. But Aster is young and developing a solid reputation as a master of the macabre and this film fits right in as far as that's concerned. Plot in brief: a group of grad students - 4 guys, one of them a Swede - plus the gf of one of the guys decide to go on a journey to their Swedish friend to enjoy the midsummer celebrations (for which Sw is justly famous). They, and we, quickly learn that the Sw student, Pelle, lives on and was raised within a extremely strict cultish community - and when the 1st day of their 10-day celebration leads to the ritualized killing of two elderly cult members, the visitors begin to freak. Though they stay! And get, of course, drawn into the cult (to varying degrees of increasing absurdity) or killed by it (w/ varying degrees of graphic horror). Sue there are oddball cults around the U.S. and around the world, but the goings-on of this cult are so absurd as to provoke laughter more than horror. A good performance by rising star Florence Pugh is wasted; so was a lot of careful attention to the design of the cult village. That said, horror such as this, in my view, works only if the filmmaker earns the buy-in of the audience; in this case, the journey of the Americans and the behavior of all never earned my buy-in for a second.
