It's Disney, therefore likely a sequel to the Disney film, and in that I believe the two Queens were amalgamated there as well. Doesn't seem so surprising.
As for weird and creepy for the sake of being weird and creepy - you definitely should read the books 'cause Burton doesn't have half the weird and creepy imagination that Carroll had.
Also, I doubt this will be creepy. Just weird. But then I'm of the opinion Burton is never or rarely actually creepy, as much as he dwells in and recites Gothic tropes and visual cues in his movies. The only thing dark is his colour palette, and even then not so in this film.
Edward Scissorhands is my best defence of that - it's a very, very sweet movie. It's odd and weird and oh so very Goth, but not creepy. Even his movies with blood in them -
Sleepy Hollow,
Sweeney Todd - have a noticeable lack of, er, edge.
