Is it really that difficult?
Okay. I'll give some people credit, it is a bit hard to figure out. However, if you've watched enough movies in the genre (including those that are bastardized and writted for the teenie bopper crowd so they can cop a cheap feel when their girlfriends hop in their laps screaming). It wasn't that hard to figure out. Let's try it from the beginning.
Group of civil war vets rob a bank and kill people. Henry Thomas accidentally kills a child. They escape to an old farmhouse en route to Mexico. The gang isn't too incredibly stable, and that's obvious when the two mutanists (mayhap too strong a term, but it gets the point across) start plotting.
When they finally reach the house, they end up shooting a creature. They don't know what it was exactly (if you watch, you learn that they are demons later on). However, they note that it has been skinned. How many people have seen skinned animals. They don't always resemble their former selves, just so you all know. A creature can become easily unidentifiable once skinned.
Anyways, gang moves on, goes in house, sees footprints. Creepy atmosphere ensues. Okay, stock for a horror film, right? Here comes the sex scene. Wait! What's this!? You don't see anything. Could it be, a director who is more focused on story than sex? Surely not in the horror genre. You jest, yes?
Anyways, so yeah, eventually, after learning something is wrong, via more possession, you learn what. Basically, in an attempt to save his wife, an old man misread slave voodoo rituals (not uncommon, people are rather stupid when grieving) and unleashed a horde of demons. Okay, so horde may be a bit intense, but you get the picture. In order to keep his secret, he hid the demon possessed family members. However, he was found out by the townspeople, and lynched. What a way to go.
So, house is abandoned, left to for the demons to run rampant within. The house is off limits for everyone in the town, they want nothing to do with the evil that is housed within. Good idea if you think about it. Anyways, you learn about the horrid demon children via flashback. You also learn how the gang came to the house in the first place.
Todd was not able to be possessed because of the gris gris he wore. Anyone who knows anything about voodoo should have recognized that. It protects him in a way. However, since they can't turn him, they torture him, and banish him.
In essence, the movie isn't that hard to follow though. If you know anything about the genre, it is fairly easy to figure out people. It wasn't a bad movie either. It wasn't glamorized beyond all sanity. It wasn't full to the brim of cheesey, yet biting, dialogue. It was an artistic approach to a film genre that has become nothing more than bloody softcore in recent years. I think it was good. Then again, that's just my opinion, and like the rest of you, I'm entitled to have that opinion.
I know it was long, but I'm done now. Sorry if I bored you.
