First of all , I didn't read the drama so I can't compare the live action . the story was good but not the kind that I was expecting . TBH , I really felt like I wasted my time , the movie was fast paced and accelerated too quickly , some elements are disconnected and some issues was left unexplained .

 Kazuya Kamenashi - was great as usual , there is no word to describe him
   Tao Tsuchiya - on the other hand this actress reallllllly annoyed me , didn't like her actin one bit , I don't know is it cuz of the character she is portraying or her acting itself  . I felt her emotions wasn't clear sometime exaggerating and sometime nothing at all
  Mahiro Takasugi - he was the greatest , incredible although his part wasn't that much but he did a great job

the music wasn't that great , nothing that will blow ur mind , but there is a surprise at the end of the movie :") (FOCUS )
There is nooooooooooo way I will watch it a gain , for me it was the worst experience

overall , that was my opinion maybe u will have a different point of view , enjoy .
Hope that my review helped  ^^
