I have to first applaud and praise the amazing work, with the roto-scoping, paintings, and hard work invested into this series by a plethora of people. It truly was mesmerizing to watch from start to finish, and the visual beauty alone could lead me to recommend this show. However, even with the style, there is a substantive element that draws viewers into the mystique of Alma's mind. It involves her reconciling, learning, and accepting her father's fatal accident in a manner that was unconventional, and explicitly suggested to be supernatural. Yet, we get hints about Alma and her father's mental conditions, which help to bring doubt into whether this entire show was just a figment of Alma's mind. It's truly walking a fine line here, and even with the last episode, I am still left unsure about Alma and her experiences up to this point. In the end, I can only say that Alma arrived at an inflection point, in which she finally finds peace with herself and accepts her mental illness diagnosis, or the perceived experiences with her father actually happened. The ending captures this show completely since it's not done, which translates perfectly to "undone." There isn't a conclusive ending, and that's the best ending for this show to ever have.
