Another review compared this to _Carnival of Souls_ or the movies of Jean Rollin, and I think that is an apt assessment.
The movie is definitely running on dream logic. It's not until the third act that we get an explanation of what is happening, and even then, it feels like the writers pulled it out of their ass: "Uh, a Satanic cult of cannibals. Yeah, that's it."
I had never heard of this movie and I'm actually surprised. This is just so bizarre and artsy that it must have a loyal fanbase.
Anyway. Not much of a story going on here. I think most people would chalk this up as the weirdest zombie movie ever made, but _Messiah of Evil_ doesn't care about your feeble attend to decrypt what is going on here. Tying up loose plot threads? "Don't have time for it!" Having a story that makes sense and isn't just weird for its own sake? "Think again, Jack!"
Ultimately I did not like this. It operates in the arthouse-garbage realm of David Lynch where bad writing can pass as depth because "you just didn't get it." That being said, I get why some people would like it. If there was just a little more focus on telling a story that makes sense, I'd be among them.
