I’m not a huge fan of HDR. I completely believe it’s the modern equivalent of colorizing a black and white film.
You are extracting light levels and colors from a film print (or in this case a computer) that the original creators had no expectations people would see.
I don’t understand why more purists aren’t against it since it isn’t the intent of the filmmakers.

I think a big problem with HDR, and a lot of reason people don’t like is less poor mastering (though there’s plenty examples of this and it certainly doesn’t help) but rather many people’s equipment. It’s meant to be viewed in a dark room, and it’s not like SDR where you can just turn up the backlight to accommodate a brighter room. Add to that most people don’t have high end displays that can get bright enough and/or have poor tonemapping, and most definitely not calibrated to reference levels, it can make HDR look very bad compared to SDR.
Dolby Vision tries to fix some of this, and does to some extent, but overall you’re not going to have a super great experience if your display isn’t up to the task
