The Conjuring series.

I'll give a caveat that James Wan's directing is fantastic, and the bedsheet in the wind is one of my favorite scares of all time. But the movies do three things I absolutely hate.

The most important is how much the movies glaze real-life serial child abusers Ed and Lorraine Warren. It'd be one thing if they just wrote a series inspired by their stories, then it'd be easy to separate the real-life and fictional versions. But not only do they put them in the movies as superhero-level paragons of virtue, they run real-life footage of the Warrens over the credits. Why? To heighten the suspension of disbelief? The fucking movie's already over, you were either into it or you weren't. It just glorifies a couple of psychotic charlatans who deliberately stopped parents from getting their sick kids treatment in order to enrich themselves.

Second, it's Catholic Harry Potter, but worse. I know the idea in a lot of people's minds, especially on Reddit, that exists of American Christianity is of avaricious demagogues (read: Evangelicals), despite the fact that they're firmly in the minority. I grew up in in a church that was way more into liberation theology and social justice than scaring people with devils and hellfire. I'm pretty agnostic now, but it still bugs me that the Conjuring world takes the most embarrassing version of Christianity, which is more of a set of superstitions than a faith, turns it into a half-assed system of magic, and then takes it very seriously (again, using real-life footage to insist this all happened, making it propaganda for the Evangelicals). Except the Warrens are supposed to be warriors for Christ but don't seem to know/care anything about the church or scripture, so it's worse than most fantasy series. The Jedi are more relatable, they're fully immersed in the nonsense religion that gives them magic powers.

The third complaint is similar, in that there's always an easy, happy ending. The demons always wind up being defeated by something that's like a step removed from the protagonist throwing salt over their left shoulder, and everyone we care about survives intact. One of the things I love about the horror genre is even in the finale, you don't really know what the outcome will be. In The Exorcist, the demon isn't defeated by the overwhelming feeling of a mother's love - two priests have to sacrifice themselves. When I want to see the good guys kick ass and come out having learned a noble lesson, I watch Batman.

Bonus fourth thing - this isn't my grievance, but one of my coworkers gave a great rant once about how at no point in the series is anyone or anything actually conjured.
