Western Horror is a strange genre. This movie itself is a bit strange. You have two or three good actors and that's about it. Some of the dialogue is so painful I had to put Bengay on my popcorn. A completely trite plot with a bit of a twist, grave robbers rob the wrong grave and get cursed. But, it's not just a curse, there's a snake bite. It explores polygamy, the grey area of outlaws, briefly touches on a marshall with convictions (before his deputy chews up the entire scene and spits it out) a strange attraction that goes nowhere, misused characters and, I'm sorry, one of the worst actresses I've ever seen in a movie. The majority of the cast tries to pretend like they're in the old west at some undetermined time. The lead actress sounds like she's ordering avacado toast. With almost every line delivery.
There are good parts. The marshall, the head outlaw and Red Feather the Native chief do a fine job. Others in the cast do a passable job for a western horror film. Near the end they try to push some messages, which are obvious. All and all, It's not everyone's cup of tea. It's much longer than it should be. The writing isn't horrible, the directing? Not bad. The acting is fifty fifty.
If you're looking for a western horror film, I'd suggest Bone Tomahawk.
