It actually looks pretty fun, too. Then again, who doesn't enjoy a good romp between a creature from Hell who inevitably fights for good? (See Hellboy, Blade). The little boy/potential Anti-Christ is named Danny. Can we assume this might be a young Danny Ketch, the person who takes the Ghost Rider persona from Johnny Blaze?
Also, noticeably absent from this trailer - which we saw in the August teaser - is ghost pee. That counts as an improvement, right?
