Does this make any sense?

A couple of things jump out at me from this article on failed children's movies, using The BFG9000 (or whatever it was) as a starting point.

The movie versions of children’s classics that have worked well in recent years—Lord of the Rings, the first Narnia movie, and Fantastic Mr. Fox, for example—stayed true to the stories and spirits of their originals

Wait, LOTR is a children's classic?

The ones that were disappointments—The Hobbit trilogy, Prince Caspian, the Divergent series—made silly changes to the original plots in order to make things easier for their audiences to understand. That sacrifice of complexity for convenience ruined the movies.

Er, no.  Not with regard to The Hobbit, anyway.  That one was ruined by the addition of gratuitous subplots not in the original, gimmicks that make no sense, and... well, see my prior three part rant.
