Has anyone seen The Last Exorcism? I mean WTF?!?!?

I saw it.

I've heard a lot of people call it bad, but I didn't think it was horrible. I thought it was good right in the middle, when the movie focuses on Nell's demonic possession. I especially thought the idea of the demon saying, "I'll count to ten, and if you stay quiet the whole time I'll let her go", everyone else agreeing, and the demon ending up breaking Nell's fingers as each segundo weent por was exceedingly clever. Because the Devil and his demons are intelligent creatures and have ways to get their own way.

But I thought the ending was kind of disappointing, when (SPOILERS);
Nell's family and friends turned out to be a Satanic cult that brought the demon to life and killed the priest and his assistants. It's like all of that action, thrill, and slight horror was built up for almost nothing.

So overall, I did like it. But I thought the ending was quite disappointing....
