This movie is dark, the book is not.
I would like to clear up a bit of the nonsense some people have stated in some of the reviews. A couple posters claimed this version of the book is "scary and dark" just like the original Lewis Carroll story. It's clear they haven't actually read the book because there's nothing dark in it – it is a whimsical look at how children perceive the world of adults. How can people, who claim to know what the book is all about, make such incorrect remarks? My guess is that they haven't actually read the book. Here is some evidence that they don't know what they are talking about:
One of the posters mentions Tweedledum and Tweedledee as key elements of the plot. These character are not in “Alice's Adventures in Wonderland,” they appear in “Through the Looking Glass.” Whether the sword fighting cards in this movie are supposed to be Tweedledum and Tweedledee is open to debate. He is further confused when he states that the Frog-Footman is supposed to be the Cook from the original story. There was a Frog-Footman in the the book but it is in fact the White Rabbit who steps in for both the Cook and the Duchess in this movie. The poster goes on to state that Alice was arrested and put on trial in the book – this is flat out wrong. The Knave of Hearts is the one on trial and Alice was never arrested.
For people claiming to know what Lewis Carroll really intended, they evidently know very little about his book. The irony is that one of those posters lamented that most people are exposed to "Alice's Adventures in Wonderland" through the various movie and T.V. adaptions rather than through reading the story. I think these gothy, pseudo-intellectual types need to stop looking for "darkness" in every piece of art they come across and get their classic literature from the books instead of American McGee.
