The Bone Eater is a fun Horror/Western with an awesome monster, (an even more awesome ghost horse) and a ecologically based plot.
When developers try to build on sacred Native American land, they awaken the Bone Eater, a terrible monster from the tribes past. The monster is pretty cool for being obviously CGI. It's made up of all bones, and looks like something from the old cartoon Skeleton Warriors. It can dissolve people by spitting acid on them or just by touching them. Later, it even gets a ghost horse to ride, which is one of the best parts of the movie. The monster (and the catchy western movie music that follows him everywhere) is the reason to watch this movie.
A reason to not watch this movie is the plot is a little trite. After the monster starts killing people, the tribe and the local law band together to find a sacred axe and destroy it. The sheriff must re-embrace his Native American heritage and reconcile with his estranged teenage daughter. So don't watch this expecting to be dazzled by the writing.
However, if you're looking to have some fun with a brainless movie, and you like great monsters, Skeleton Warriors, or cheesy horror westerns, this would make a great choice for you.
