The theme of the movie is about great love. Even if it becomes a zombie, even if it loses its humanity, it still restarts the heartbeat due to the simplest intimate action. What moved me the most was that many zombies looked at the hands holding hands in the glass window together. At that time, I really felt that human beings couldn't let go of their emotions.
There is another point that may not be mentioned by many people. I think this movie has a pretty good explanation for "zombies eating brains": because I have no past memories, I can only get other people's memories by eating brains, thus Feel the joy and sorrow. (Of course this is unethical)
However, this movie also has some flaws. Others have said a lot, so I won't go into details.
