Seen it yesterday and I thought it was pretty good. I understand the comments above that it doesn't really resemble the book, but that's not the idea behind the film either I think. Alice is already 19 here, so it's when she's goes back down the rabbit hole. So it's actually an entirely different story, with some correlations to the book by C.S. Lewis.
Watched it....well could have been better, yes expected more, but went open minded so many things wrong but some things were right, Jonny Depp was brilliant as the mad hatter and the mad hare was my favourite character. every1 else not good.. doormouse i found annoying, but on the whole Tim Burtons worst film, but has to be said his worst is still better than mosts 'bests'
