I believe I commented on this after the last trailer we saw, with her waking up to see the Cheshire cat.
As interesting as the original concept American Mcgee used, I'm not sure if it will be as awesome when the idea isn't all that new. What's more "Wonderland" has been revisited a ton of differant times in the very recent past, all with dark spins on the idea. To some extent this seems like a combination cash in, and American Mcgee more or less giving a reminder that he was one of the first people to do it. I'm less excited than I probably should be given my general love of wierd stuff.
Truthfully if people are going to explore the concept of dark versions of classic children's fantasy, I honestly think they should be turning an eye more towards things like "Oz" or other fairy tales like "Hansel and Gretal" or whatever. The reason being that while all of these things have been done, they are less treaded right now than "Wonderland" is. Perhaps I'm unusual but I tend to rapidly become less and less impressed as I see more of the same thing.
Also to be entirely honest if someone DID want to do something fairly unique, the above artwork of "Strawberry Shortcake" touches on a fairly good idea. Especially during the 1980s a lot of bright, cheerful, and upbeat worlds were created to entertain young children who are now adults. A good portion of those liscences have also fallen more or less into obscurity and don't seem to be in use. Doing really dark and menacing versions of those worlds could be interesting, perhaps even if one was to say that most of them existed in some kind of shared cosm.
I'll also say that I think Todd Mcfarlane arguably came up with the definitive vision of dark, sexy, menacing takes on fairy tales and such. Sadly I couldn't collect the figures at the time (no place to keep them mostly) but his monsterous, bondage and carnage obsessed takes on things like "Oz", "Miss Muffet", and others were quite interesting.
