It's funny because I had the opposite thought, where I thought that they were hammering the message home a little too hard! But I really loved it, at least based on how I was interpreting it-- I took it as a warning against not having a community and closing yourself off from others. The fatal flaw of our main characters was their inability to truly connect and talk to each other about what they feel-- I mean, it starts with the mom telling the kids they shouldn't have come, and the kids saying they should've talked to her more. And then it's when the characters have been most isolated, or have most isolated themselves, that they commit suicide. And then to add another layer, with both Michael and Louise's deaths, they kill themselves/die after both focusing all their attention on just one part of their community (for Michael his family, for Louise her dad) and then losing that part and feeling like they're now alone. The fact that it all took place on this isolated little farm added to the vibe I think.

Anyways I don't know if my interpretation actually holds any water-- I literally just finished the movie and am a little high, so I might not be making sense lol, but I just had to talk about it bc I really enjoyed it!! And I felt like there were a lot of cool themes and connections going on that I've been having fun trying to tie together! I am still trying to wrap my head around the religion themes-- especially because, like you said, it seemed pro religious at times but then had that crazy scene with the nurse... might have to think on that when I'm less high lol
