The prospect of watching a semi-animated show didn’t exactly thrill me, and the way they did the trailers also made me rather nervous. So I’m very happy to find that I’m really loving the way they’ve adapted the cells! It fits perfectly, and the transitions between the real world and Yumi’s headscape are impeccable,” said a Redditor.
