Like most Burton films, it was highly visual, but with little emphasis on plot, pacing, & character development.
Most characters were a bit bland, with Alice (Mia Wasikowska) & White Queen (Anne Hathaway) being annoying. In their defenses, they clearly were acting as directed (e.g., Alice being kind of whiny & the White Queen prancing about like a ballerina on ecstasy). But the movie was saved by Queen of Hearts (Helena Bonham Carter), Mad Hatter (Johnny Depp), & most of the animated characters.
Bottom line: It’s a pretty fantasy movie, but is slow-paced in parts & not very cohesive. Also, try to focus on the good characters, who might compensate for the really bad acting from other characters.
