Jackson is covering his tracks. The REAL reason the Hobbit movies sucked, was Jackson made it just too long, squeezing the last dollar out of the franchise.
Well, that and the insane changes he made to the very fabric of the story. A Dwarf, hooking up with an Elf maiden? And no where in the story line do I recall warrior elf chicks.
No, Tolkein spun an almost perfect tale, and Jackson messed it up.
