When I started to watch this drama, I gave it "7" at the beginning. The characters were older than in original story, and the first two episodes felt like "yet another 'rom-com' story". I must admit that the story grew on me very much with every episode that I watched. The Cast was great. If you find most of main actresses annoying or 'weak' in character, in this drama you will find a different character. Role of Aibu Saki is refreshing and sweet, but definitely not annoying. I can't be objective about Mizushima Hiro, so ... for me he was as good as always. And finally - Hayami Mokomichi. He was great in depicting the robot. Of course his moves were strenghten with specific sounds but still, through the whole series he even always blinked automatically. When it comes to music, you don't hear it much mainly because of focusing on the plot (at least that was the case for me). But Ayaka's theme song "Okaeri" has certain strenght to it, and it will definitely grow on everyone (especially combined with perfectly done visuals at the end of each episode). After some time, I feel like I would like to come back to this title very much, and that does not happen often. I think there is something special in many Japanese dramas. How even seemingly simple stories capture your attention, your mind, your heart. Thanks to great acting, great plot, nice theme song... Zettai Kareshi, in my opinion, is one of those memorable titles. Definitely WORTH seeing.
