I thought overall it was a really good film, though there was a notable dip the last 20 minutes or so for me. The aforementioned "dance" was probably the worst part, but I think it was supposed to jar in a sense but the problem was that it didn't really work. Other than that the one aspect I disliked was the character of Stayne and his whole sub plot. If they had a gotten a decent ham actor in the Tim Currey mould it might have worked, but the actor in the part was totally wooden and unconvincing.
I thought the portrayal of most of the other notable characters was rather good: Depp, of course, had a lot of fun with the Mad Hatter, Bonham Carter was surprisingly convincing as The Red Queen and Stephen Fry probably put in the best "performance" of the lot as The Cheshire Cat.
Mia Wasikowska's turn as Alice was interesting, in that while Alice was uncertain and lacking in confidence she sold the character really well, but was less convincing as the film neared it's end, specifically the last scene above ground.
The storyline was interesting up to the point where the big battle was revealed. I actually liked the fact that they were not trying to just re tell the traditional story straight up, but that they rather acknowledged strong elements both as the story progressed and retrospectively. But when it took a turn towarRAB Narnia , i feel it lost it's way rather.
Visually it looked pretty good: not as gorgeous as some Burton films though, to be fair, but good nonetheless.
I guess I'd rate this around 7.5/10.
