It pretty much hit me with full force. I'm not sure how old it is, but I take it to be less than year, I'm not sure.
I loved this movie.
For one, it was an anime movie (well animated, too) that is split into 3 episodes, and it is about the distance between two lovers (sounds familiar?

Moving and tragic, but so well done... Definitely one of my favorites. I didn't cry, but I'm sure if I had been a little more soft, I would have!
The title, though it seems to have nothing to do with anything, is in relation to the speed at which Sakura (cherry blossoms) fall to the ground: 5 cm per second.
For those who haven't watched this movie, if you're interested in a good watch, I suggest this movie. I haven't met a person who didn't like it yet, but I do wonder about others' opinions.
Also, even if you're not interested in the movie, I suggest you listen to the ending song. One More time, One More Chance preformed by Yamazaki Masayoshi, was pretty great. The lyrics were really fitting and nice, too.
