If the movie were traditional CGI superimposed over live action it wouldn't look very good. I could name 20 examples...just doesn't work. An animated film has the added benefit of not needing to build a prop dragon
Considering the vast number of animated movies that look spectacular 50+ years later, plus Zemeckis, I've giving this movie the benefit of the doubt.
PS: Jolie "nude" does not include "naughty bits covered in honey" unless a CGI Hilary Swank is "licking it off her".
