Koizora [恋空] Its ok [spoilers] [Rating: 5/10] The movie is a lot better since its not soo long unlike the drama.
Now, i have to appreciate the drama in someway also, cause they fill stuff that in the movie left you in the air. For example, how he finds out about his disease.
Give it a chance, you might actually like it.
Like someone said before they kinda portrayed Hiro more violent when in the movie he was never shown that way or even forceful.
