This series is mature, suitable for adults to watch, but the plot is rather boring. The whole movement ideas thing is not that interesting unless you are interested in this topic. I would like to see Kamen Rider fight monsters, not a movement to protect monster who can shapeshift into humans, and to provide them their own rights in society. This movement concept can be included in a different original shows, movies, or to not include it. Ended up dropping this show several episodes later and have not gone back to it ever since. If Toei want to remake Black Sun then they can just combine the live action source materials and manga together. This remake is going somewhere for older audiences, but the story was not it unless you enjoy those topic.
