After about a month of excitement and anticipation, I finally saw it today! *Fangirls.*
I thought the movie did a really good job of capturing the Wonderland (or Underland =P) atmosphere. They used many of the characters from the books, yet gave them a special twist and more personality.
Alice herself didn't seem to have much character -- some of the creatures/people overflowed with their personality (the Cheshire Cat or even the March Hare), but she never seemed to really define herself as anything but the hero. I could tell what they were trying to do with her, but I think the scriptwriters could have given her more spirit.
The effects, however, were as amazing as people claim. Probably more than half the characters were partly or all CGI (in some scenes, there weren't even any real people at all), but it was incorporated very well. The Cheshire Cat's appearing and disappearing effects are aaaaawesome! =D I'll bet it's even more stunning in 3D.
The Mad Hatter was like Jack Sparrow, Willy Wonka, an occasional Scottish accent, and an awesome hat combined into a teapot and stirred vigorously for five minutes, then served. Johnny Depp is just really good at playing slightly (or more than slightly) insane yet likable characters.
The one thing I really didn't like about it...
(Spoiler'd for those who have yet to see it)
(If you haven't seen it, don't peek!)
(I know how hard it is to resist clicking that button, but I grant you willpower! YOU HAVE THE WILLPOWER! *Summons globe of sparkling willpower and emails it to you*)...
Ending on a boat seemed to me almost like symbolizing her sailing away from Underland and moving on to the adult world, as she's moving farther and farther away from the rabbit hole. I was really shocked when they ended it right there. =/ What would have made more sense, in my opinion, would be for her to run back to the hole and whisper, "Just wait for me!" or something like that, then walked away as it faded to credits. What would have been even cooler is, instead of the caterpillar dude reappearing at the end, it turning out that the Hatter had come after her and was a sailor on the boat or something. Then he could have braided his hair and they could have become pirates and bravely sailed the seven seas, searching for dead man's chests and... no, wait...
Fantasizing aside, the ending seemed kind of cut off, like they weren't sure what to use as the ending. My best guess is they're hoping that, if it's popular enough, then can add a sequel. But still... it lacked in... muchness. ;.;
Okay, sorry about the rant. <=D I'm done now, honest.
And, on a different note, here's some random fanart I drew while waiting for the movie to come to theaters!
