I thought the visual style of the species in Narnia was distinct enough anyway. It's not like they had hordes of Urukhai.
they almost did.
And also... I think the visual style (framing, various shots, cinematography, grading, props, costumes, places, set pieces) mimicked LOTR to
an obvious extent... and on top of that, the script, acting, and directing were lacking drama, pace, and an overall sense of "wonder" to the film. It felt
like your typical disney-channel adventure movie... Narnia is worth more than that.
that's why I say this film is not very well made. and what the crap is up with that american-yank wolf!?
