This Alice in Wonderland did not have enough Wonder. It was terribly predictable and for a sequel, it lacked enough new characters to make it interesting. The characters that were present were not developed and because of that fact you did not care much about them or the outcome of the film. Johnny Depp's talent was wasted on a supporting role that actually needed to be featured more.
Overall, I felt it was a disapointment from some otherwise very talented directors, producers and actors.
