I'll admit right up front, this movie confused the heck out of me. I'm math-phobic, and time travel and space-time continuum type things relate to math, and you see my dilemma. But that's just me.

The story was beautiful and sad. I need happy endings, and unless I completely missed what was going on, this did not have a happy ending. I spent the time getting to know and love the characters, and once they knew what was going on, I could almost feel their pain in the knowledge they had gleaned. Japan knows how to do beautiful filming that is kind of "slice of life". Everyday places and everyday stories take on new and deeper meanings, and I love that.

Both actors did a wonderful job with their parts. I've only seen either of them in one other work, so I'm going to need to check out their filmography and expand on that.

Music - was there music? I wasn't paying attention to that.

Rewatch value - I'd say definitely, if for no other reason than trying to figure out the timeline.
