So I finally actually watched the free first episode they put on iTunes, and wow has this show changed since December.
I saw the same episode, but it was much, much shorter. About 7-11 minutes I think? There was only Dipper, Mabel, and Grunkle Stan at that point, no extra help from around the shop. A LOT of new gags too, the leaf blower kiss bit wasn't in the version I saw. In fact the one I saw had a completely different ending. And beginning too, IIRC, I don't think the journal was found in the same way. I wonder if what I saw was just the pitch episode and once it'd been approved for series they fleshed it out into a full episode?
Anyway, awesome show. Very very cool to see how the idea grew since I saw it. Still funny as hell, too, I really like the new characters.
