That is true. However, we did get a few good films. The Chronicles of Narnia was alright. So was the incredibly underrated "The Last Unicorn." The first Discworld film is considered incredibly good. And the craze led to Game of Thrones getting greenlit.
This just made something occur to me: without the 2000s fantasy craze, would there still be a Discworld Cinematic Universe in development? On the one hand there'd be no precedent with
Discworld: The Colour of Magic and
Discworld: Sourcery (well, the latter may be an advantage...) but on the other hand shared universes for films are big right now and Discworld is pretty much the perfect source material. Or perhaps there would be a DWCU but it'd have to start with
The Colour of Magic rather than the
Mort movie they're making now.
