Where to begin? This is possibly the weirdest and most surprising dorama I've ever come across. Nothing is what is expected, or what it seems. It's just as hard to define its genre, because while it could be listed as a science fiction drama, the fantasy part is just a device to make a very human, touching and very present message come across: are we really capable of cherishing our lives? Do we truly appreciate all the little and big things thrown onto our path or do we give them for granted? Were I to base the overall rating only on how much I liked it, I would give it a 10. But it's undeniable that it doesn't deserve it on the cinematographic level: the shooting quality is average at best, it reminded me of those catastrophe movies from the 70ies, like Poseidon, or Empire of the Ants, often naive, with some ludicrous special effects. And it certainly does not shine for its photography. The music goes from ordinary to completely random. But characterization, dialogues and acting make up in heaps for whatever flaw. If you have read The Lord of The Flies by William Golding, this drama may remind you of it. Mix it with the most classical concept of Carpe Diem - seize the day - and you have Long Love Letter. Kubozuka Yousuke is adorable here, at times childishly clumsy, at others emotionally intense. But it's Takako Tokiwa who really steals the screen, her character being the epitome of strength of will, sweetness and courage. In fact, this drama is acutely feminine, like mother Earth herself. The kids play their part very well, one ends up liking a quite stony Yamashita Tomohisa too. I adored the ending. It makes this into one of those dramas one is emotionally compelled to talk about with someone, share opinions and questions. Like it or not, it doesn't leave you untouched. So, by now you have 2 choices: decide that both the drama and the reviewer are deranged and leave it be, or watch it.
