I didn't think that teaming Obi-Wan Kenobi with a talking horse was a good idea, but even I didn't expect this. This first trailer, the one with Mr. Pink delivering the only bit of dialogue, was actually good. But the subsequent offerings made it look worse and worse. The brown artwork probably didn't help. Apparently the more the horse talked, the less people wanted to see it.
I know for a fact that Mr. Large Body of Water Partially Surrounded by Land is very involved in the marketing of his movies, so he's got to share some of the blame. Maybe most of it. After all, he's the one that cast the horse.
