I had a real hard time trying to figure out a score for this film, much less an overall impression of it. Frankly, you just don't see film like this any more.
I can understand if some audiences don't get it, mainly because it feels like the Star Wars Holiday Special on a severe drug bender. But once you peel away the Sasquatch mating rituals, birthing scene and other idiosyncrasies that make up this experience, you start to piece together the meaning the Zellner brothers were most likely seeking. They posit the reason why we don't see sasquatches is because they just don't exist anymore.
Like the last days of a failing empire, this very well might be the last Sasquatch family in the Pacific Northwest. Some people won't like the reasoning behind it, but it's the usual blame falling on deforestation and human infringement. I'm sure some might derive more meaning, but this is the base understanding I took away from this film.
Sasquatch Sunset is definitely not for everyone, but if you are a curious film goer, you might find something interesting in this bizarre and completely one of a kind movie. Just be ready for weird nature stuff....because I sure wasn't.
