Even though Christina Ricci did good voice over work in the first movie, Kate Higgins voice over work in the others was actually very good. But that's my opinion.

I liked both, but I thought Christina Ricci's voice sounded better for the character. That's how I feel about all the characters who reappeared in 2 and 3. I'd even like to see the actors who dropped out back—Joel Edgerton as King, Bruce Willis as Tony, Cathy Griffin as Claudette, Jennifer Aniston as Princess, Jesse Eisenberg as Stinky, Daniel Radcliffe as Runt; some of these were confirmed early on, but changed, while some I'm assuming based on how the actors/actresses sound—in later sequels.
