There being 2 endings didn't help my mind when I watched it a second time and had a completely different experience.... I was like, wtf, I know this is the same movie, but why do I feel so very different.

Ugh fuck just about everything about this movie. It was a masterpiece.

Let's put extremely normal and relatable people into a pretty normal situation with pretty good intentions, then let's have them do a somewhat risky hobby in a somewhat stressful environment, then let's have normal reactions to some pretty fucked up, high stress situations, then let's fucking have some pretty fucked up relationship stuff come out and some pretty understandable reactions to it, then let's add some fucking fucked up fucking fuck fucks who may or may not be human and may or may not be looking to eat or just getting off on fucking people up. And then let's have just the tiniest but it reminder of normalcy fuck up everything that wasn't fucked before. And then you don't know which ending you're getting, and you don't know which one is technically better for the characters.
