This is gonna be a short review because I've never written one before and because my english suck.

BEWARE : MAY CONTAIN SPOILERS:

The first thought who popped into my mind when I finished this manga was, oddly, his similarities to Hachimitsu to Clover (Honey and Clover). The stories aren't the same, nor is one a copycat of another, but they do share an interesting trope of the "tragic prodigy" (for lack of a better term) shared between Hagumi Hanamoto and Kaori Miyazono. And Kousei too, I guess : if their abilities as genius won't fail them, their bodies will.
And it's funny. Take Tsubaki and Yamada, for instance. They're both fit, strong girls, whereas Hagumi and Kaori are rather frail. Normal people are healthy and well in their skin, while for people with outstanding artistic abilities, the body mostly gets in the way. And who say body also say time and time restriction : the body never have enough time to finish what the mind started.

Well, anyway, that's enough for dorkish me. For the review : the main annoyance with "Your Lie in April" was the repetitiveness of certain elements, aka flashbacks, characters's private thoughts, etc; and if it wasn't repetitive, it just dragged too much. I know some of this repetitiveness was probably necessary to really show... stuff (like how much the memory of Kousei's mother still haunt him) but I don't know... it bored me anyway. Or the "bottom of the ocean" trope : we got it the first time, no need to bring it over and over again. And just sometimes, it gets a tiny bit too cliché, or with a symbolic a tad to obvious (hint : when Kousei jump off the bridge with Kaori...)

That said, I'm still giving it an 8 outta 10, because 1) it made me cry, and 2) it inspired me. Big time. And somehow, it managed to keep me up way too late at night for almost a whole week. So as a work of art, it served its purpose. For me at least :D
