Alice in Wonderland - Pretty good. Kept me amused. Don't bother watching it in 3D; unlike Avatar, the 3D was mostly used for tacky "WHOA COMIN' RIGHT ATCHA!" moments, so it didn't justify the use of the technology to me. March Hare was my favorite character for whatever reason; dude does way too much amphetamines kno'm'say'm? Storyline was kinda silly but duh.
To all the people going "I don't get the change at the end" . . . from a storytelling perspective, yes the ending is trite, done before, and doesn't really make much sense since Alice doesn't have that much of an impetus to change. However, if you're taking the entire movie as a metaphor for Alice going off and doing hallucinogens in the forest (not that far out there), it makes enough sense. LSD/mushrooms/etc are a time of seeing lots of weird shit and also completely re-evaluating your worldview so it worked as far as I'm concerned in that framework.
And, honestly, if you're going to take issue with that, you might as well take issue with a Victorian-era young woman having anything to do with a business and not simply getting married to the person her parents had arranged for her. And if you're doing that, you are spending too much time trying to analyse the plot of a movie where A LITTLE GIRL SLAYS A DRAGON.
Anyway, it definitely is Lewis Carol meets Tim Burton meets Johnny Depp so it's worth seeing regardless of the amounts of drugs you do. It's also just way better if you do because they certainly kept the innuendo up and the little nods will make you smile.
