And here I was thinking that you were referring to the live-action version. Hehehe.
Well, it had nothing really new to offer in terms of plot lines but it was still a tearjerker.
I can understand why some people would give it a negative review, after all they're not Japanese to begin with. But serioulsy, I was really looking forward to something cooler in it but it had kind of a unique twist at the ending and I was also kind of hoping the main character's relative would shed some light into it by relating her own chrono-experiences.
