I read a book a few weeks ago and I decided to watch the movie adaptation, too. I have to say the book was better detailed but the movie was much more emotional. In the book there were more scenes with the devil but in the movie more moments with cats. If I had to rate them I would give 9/10.
Actually that wasn't a bad live action adaptation. It had the most important scenes from anime but still missed the significant events as school festival or school trip where they should've kissed each other (and of course accidentally too). Other than that it was quite good. 7/10
Honestly, I enjoyed watching the original version much more. In my opinion, the live action movie was too long. They added so many unnecessary scenes so for many people it could've been kind of boring. But, I'm glad they added Yamazaki Masayoshi's hit song "One more time, one more chance". My overall rating: 7/10
I have to say this movie was so different from the original. I didn't like anime but this was even worst. Overall, boring and not funny at all. I can only recommend it to Moka's or the boys' from the main cast fans.
Thank you so much! I'm really grateful because I love Moka Kamishiraishi. But, I need to watch anime first. I'll let you know if I enjoyed watching it!

Also, that was my 100th drama.
