I don't want slag on this film too much since it was clearly made on the cheap and in earnest, but it's full of needless, wobbly German dialog, and it's just such a puzzling decision. Most of actors obviously don't speak German; the writers don't speak German at the level you need to write a film. Why is half the film in German? Yeah, a couple of the actors sound at least fluent, but they're certainly not native, and the constantly shifting fake German accents when they (almost randomly) speak English are just bad. There's even a point in the film where the supernatural baddies explain that they speak all languages, so one is prompted to wonder why they decided 2nd year college German with subtitles was the one to go with.
I could also grumble about this sophomoric understanding of Cernunnos and pagan worship in general. I'm not sure the writers get the basic concept of blood sacrifice (or what the word "demigod" means), but in the tradition of plot motivations for horror films, it's hardly the worst offender. Unfortunately, it kinda misses on the whole horror thing too. And some of the dialog: "The panther and the sheep never hunt together."?
There's some decent acting and some sorta decent production (again, I give them points for at least trying), but for the most part, it seems like a somewhat long student film that by some miracle ended up on Amazon Prime.
