Someone on Twitter wrote, "I absolutely detest the idea that storytelling has to be dark and tragic to be "mature". Happiness is not childish. Just because our world is fucked up doesn't mean that all art has to reflect that."
I think Sunny is one of those happy art.
Sunny may not have much substance, it may never really address any real hard issues in its story, like the hardships of being young in a military dictatorship, or the youngsters uprise, it didn't even delve deeper to some of its main characters' hard life, maybe the problems are too easily solved, and maybe Sunny doesn't really say anything of importance. But, maybe, sometimes that's enough. Sometimes just a funny, outrageous, heartfelt, bitter-sweet story about female coming of age and friendship is enough. It isn't any less important, real, or substantial.
