I watched this film when I was sick with bronchitis. I was glued to the couch, coughing and hacking, watching this movie and wondering if I was hallucinating, or if the movie was really this freaking weird. The answer is a resounding 'yes.' This movie really is extremely weird.
YellowBrickRoad is an assault on the senses, and I believe that was completely intentional. The visuals, the characters' reactions, the never-ending path, the hopelessness, the desperation, the cacophonous sounds-- all of these things created a unique and subtly terrifying environment. That said, I didn't necessarily find the movie scary, but I did find myself thinking about it for a few days after watching it.
But, I wanted to like the movie more. I wanted more substance. I love movies with an pseudo-historical backdrop, and I wanted to know more about the town's former inhabitants and the path. I guess I wanted a bit more investigation and a bit less acid trip. Yet, I was left with the impression that the semblance of an acid trip was the writers' and director's intention.
So, if you keep the film within its hallucinatory context of a deconstructed and wholly disturbing reality, you might glean some enjoyment out of it. Don't expect your typical horror fare, though, because this is a strangely unique plate that almost borders on experimental.
