Tbh I don't really like this trend of making Alice older, and while I loved OUATIW one of my biggest critiques is that they didn't keep Alice Millie's age. Obviously that would have changed the plot significantly (no Cylice romance, less developed swordfighting skills, etc.) but I think overall it would have been an improvement. That said, I think Once's take on Alice (and Wonderland in general) was the best of the three, and Sophie would be my next choice.

I've never seen Caterina's version, Mia's was really bland and boring, and Sophie's is one of the WORST actresses I've ever seen and the character was irritating. Millie was a pretty solid Alice in my opinion.
