By biggest beef, right off the bat is adult Alice. That alone is enough to ruin it for me.
If he were doing something along the lines of American McGee's Alice, I wouldn't have a problem with it, but if he's retelling the original story, her being an adult removes a large portion of the point of the book.
Actually, Burton's film will be more like a sequel story.
The idea here is that she is 19 now. She finds out that, at a party she and her parents are attending, she is to be proposed to. Freaking out, she flees and ends up stumbling down the rabbit hole. From there, she returns to Wonderland, lacking any memory of having been there and finding a rebellion emerging against the Queen of Hearts.
