In this movie, Alice Kingsleigh returns to the magical world of Underland, where she finds out that her friend, the Mad Hatter, is very sad and sick. He believes his family, who disappeared many years ago, might still be alive. To help him, Alice must travel back in time using a magical machine called the Chronosphere.

During her journey, she meets younger versions of the characters we already know, like the Red Queen and the White Queen. She also learns more about their past and the reasons behind their actions. One of the main messages of the film is that we cannot change the past, but we can learn from it and make better choices in the present.

The movie has amazing visual effects, colorful costumes, and a great cast, including Mia Wasikowska as Alice and Johnny Depp as the Mad Hatter. I enjoyed the movie because it combines action, emotion, and fantasy in a very creative way.
