Usually for big budget films they sacrifices decent scripts ala Transformers trilogy. Also taking in consideration the 'Monster' genres these types of movies usually suffer from terrible dialogue and over-saturated action scenes. I think Del Toro did a masterful job having the battles elegantly played out, and compressing the story without sacrificing character development into an enjoyable 2013 'Monster' flick.
Visually stunning for the first 2-mintues of the introduction of the Henson inspired CGI/puppetry later seamlessly meshing into the dreary background of bland colors used in the film. From director Spike Jonze "to make a movie about childhood rather than to create a children's movie." with a niche idea the end result was a drawn out one-dimensional gloomy and depressive movie with a self-fulfilling ending all pitched to who?
