@Lazlo, etc:
While technically it may be a "Jim Henson Company film", its really
a Dave Mckean film. It wasnt spose to have a classic Creature Shop look. If you go on youtube and type in "Dave Mckean short"
youll see how MirrorMask looks EXACTLY like all his other amazing music videos and short films.
MirrorMask was amazing, and as a huge Mckean fan since the late 1980's it was so great to see a feature film of his work. In fact I saw it twice in theaters, driving almost two hours the first time.
Again, its really a film for fans of Neil Gaiman/Dave Mckean, and of surrealism than it is for people expecting Creature Shop. The look to me isnt cheap in the least, they could have had 300 million ala Avatar and I would have wanted it to have the same look.
*just rewatched the dvd the other night*
Also...Pan's Labyrinth while rather brutal at times, actually does have a bit of a creature shop feel to it.
