Okay, this clip is awesome for so many reasons. It really isn't 'terrible' at all. It's really just horrifying. Here's what I like about it.
1. The kids speak to the devil as if he is their new best friend, even though he sounds like Thom Yorke crying through a low pass filter-sweep.
2. At 1:51, the girl looks like she's about to light an apple to smoke out of.
3. Mark Twain doesn't give a fuck about those kids, and he just stands there and thinks while they enter hell.
4. No child could watch this and not cry. I almost did.
