Not to drive this into the Preacher love fest, but yeah it was pretty fantastic. It's exactly what I wanted it to be. Keep in mind, I've never read the comics, which is interesting because I was reading the comments on a review and a lot of people were saying how non-readers would be lost and couldn't get into it, that wasn't the case for me.
Ok as for horror nights, I can see where they could pull scenes, but I'd rather them wait until next year to do it, they finalized the list back in December and I don't think that was enough time to give the OK on it. Now yes like you said, they've pulled risks like Crimson Peak and Dracula Untold(don't really agree with the From Dusk Til Dawn example) and did the mazes without the audience knowing what to expect. I think both of those cases was universal wanting free promotion. They don't really have any obligation to AMC(unless they made them do it to have walking dead stuff). Even though those houses were really good, I don't see them doing it. I don't see John passing on Krampus but keeping Preacher.
I almost forgot to write my repent because Jesus is cumming lime
