It PAINS me to rate this an average score, but damn that ending.
Absolutely no spoilers, but to ME, personally the climax, or more accurately, the last few moments, were such an incredible letdown. YOU or anyone may love it, and more power to you. So, I'm not really trying to discourage anyone from making it to the end. Hopefully, you'll get more out of it than me.
UP to that point...I really dug this movie. The atmosphere, tension building, acting, cinematography...ALL so top notch, you'd think you were watching a $50 million-dollar Hollywood film. In fact, I was so amazed during this movie, I was wondering why most Hollywood movies I see aren't half as good as this talent.
The film revolves around a family tragedy that leaves a single mom to raise her two daughters, the older of which is somehow transformed one night in the woods near a party she was attending and now...she won't eat. Okay, there's more to this, as expected, but her lack of eating, mood-swings and possible premonitions will increase alongside her mother's desperation to help her.
This is labelled as "horror," but I'd put it more as a slow-burn suspense/family drama. And I've seen movies like this before and no offense to this cast/crew, but much better. Such as the real horror movie, Raw. There was also a segment of the horror anthology, XX, called "The Box" - also, much better.
Still, it was fantastic to the end and I'll leave it up to you if you decide they did the story justice with their conclusion.

Final Thoughts: Completely different movie, but I would also compare this slightly to 2021's Malignant. And that's only a small part of A Banquet. Please know, I loved Malignant 3x more overall. Still, I felt the need to bring it up.
