Well, what can you say for an anime that lasts 1m 27s :S.
It's essentially a type of romantic thing that i suppose is fairly typical in theme to much of Shinkai's work. It's a sort of silent movie with two characters simply talking about their relationship. Everything within is essentially designed to be simplistic, from the b+w colouring to the absence of spoken dialogue which I think works well within its own context. For something so short I thought it was fairly enjoyable.
