1 litre of tears... the title is no joke. What can I say? It's my favorite Asian drama of all time, and with good reason. The story (which is based off real events from Aya's dairy) transitions well onto this on screen drama about a girl who struggles with finding happiness within herself and seeing the ones she loves struggle with the obstacles that come with her disease. Ericka Sawajiri's acting could not have been better, the way she portrayed the disease slowly progressing episode by episode was truly what made this drama feel so real. The supporting family actors were phenomenal as well, especially the father,mother, and older sister. They were the ones that gave insight on what a family has to deal with when someone is striken ill. Ryo Nishikido's character was a great fictional add on, the slight romance between him and Aya was simple and sweet...even if it made your heart burst. Musical score was great, with many amazing acts and bands who's songs fit with every heart-wrenching scene and flowed with each tear. This drama will make you question, "what if this was my family?" Which is why i think so many people can relate to it on an emotional level so well. GO WATCH IT :)
