To tell you the truth, I'm not the biggest fan of the original stories. I went to see this 3-D movie because it's directed by Tim Burton. The movie is a sequel, taking place 13 years after Alice's original adventures in Underland. A twenty-year old Alice (Mia Wasikowska) is proposed to by a Lord of a rich family but says she needs a moment to think about it and disappears down the rabbit hole after following the rabbit with the stopwatch. She finds herself in an old looking room and first drinks a potion that makes her smaller, then one that makes her larger. She shrinks back down to go through a small door and is reintroduced to the Mad Hatter (Johnny Depp), who is glad that she returned. They all go to see the blue caterpillar who explains that she has a destiny to slay the Red Queen's creature, The Jabberwocky (voice of Christopher Lee). Once she does this the White Queen (Anne Hathaway) and take back her kingdom from her evil big-headed sister.
This sequel is a well-crafted movie with its bits of Tim Burton weirdness (with the Mad Hatter) but it also seems too influenced by Lord of the Rings, especially the battle between the forces of the Red and White Queens. In fact, the ending, when she returns to her "real" world is like that scene from WIZARD OF OZ when Dorothy returns to Kansas. The 3-D is not nearly as good as that of AVATAR and is primarily effective with the flying creatures and peripheral effects. By the time the battle with the dragon happened I forgot I was watching 3-D.
I think my main gripe is there's no emotional connection with characters so I didn't much care what happened to them. Tim Burton's ALICE IN WONDERLAND is definitely one of his lesser endeavors.
