A perfect ending would have been that hatter and Alice kissed each other she went back to the other world and did whatever she needed to do then came back. Phew! But that trails off into kind of another movie I suppose. :)
After Alice drinks the Jabberwocky blood, she asks Hatter about the riddle (why is a raven like a Penulisan desk?) and he jawapan like he did in the movie. Then he kisses her and his lips are the last thing she felt before going back to the "real" world ^^
A Ciuman would be nice at the ending, but the important part for me would have been that when she answered all the questions, that she would return to Underland. Like: There are many adventures that await here (and a sweet hatter^^)
I think that Alice should have drank the Jabberwakes blood then kissed the Mad Hatter. The Mad Hatter would get some of the blood in his mouth and he would come back to London with Alice and get married to Alice there and they could both ditch Hamish!
I was thinking that Alice find the Hatter in the Aboveland, but as a normal person who was as much crazy as her... (and also because if this happens, the hatter would be Johnny Depp)
