Yep. Disney isn't interested in creativity here, just formula, and this formula film will make a bazillion dollars. They'll only stop churning out this crap if people stop going to the theater to see it.
The Hobbit was almost THREE hours long, and the extended edition was just over that mark. A far cry from 2 hours, which seems to be the standard length for most modern commercial films. ;)
I realize I'm stating the obvious here, but after watching the trailer this looks like just another Disney money grab. There is, in my mind, absolutely no other reason for this film to exist. I have zero desire to see it.
