I think Moria hits the nail on the head with this:
It feels increasingly as though Tim Burton has sealed himself in a hermetic world – always working with the same stars (Johnny Depp, Helena Bonham Carter), the same musician (Danny Elfman) and frequently the same designers and writers. He has become like Picasso, Anne Rice and George Lucas – someone who had a big hit and found acclaim early in their careers and spent the ensuing decades recycling the same thing in slightly different forms, rather than exploring new directions.Slant gives it a mixed review. Salon.com says, "I found myself trying so hard to like “Alice in Wonderland” that the process of watching it exhausted me." Roger Ebert says, "The film is enchanting in its mordant way until, unfortunately, it arrives at its third act." Rotten Tomatoes gives it 51%.
