The film looks..Interesting. But I dont like the effects too much, seems like its all CG. You can do a Alice in Wonderland movie without too much CG, to prove my point heres a clip from the film Dream Child, with effects by Henson Studios.
(Sorry For The Quality, I didnt make it, but I couldn't find anything better.)
I really want to see this in 3D; when I was watching A Christmas Carol in 3D last weekend this was on the commercials before the movie and it looked very interesting, so I'm gonna go see this for sure.
