This movie was very touching but I feel like it was missing some key details such as back stories. I would have loved to have seen how Wonderland was developed or how some characters have died/ what happened to them in order to be in Wonderland. I think this movie could have been made into a show to better grasp the true functionality of Wonderland. I adore Bae Suzy and Park Bogum and hope to see them act together in another production soon.
