Okay. So these girls are funny in the good kind of way. i pictured them as like Momoko and Ichigo (haha... Kamikaze Girls reference) alongside Haruhi Suzumiya (do I really have to reference?!) They are dedicated in their own ways and mindsets to be official rangers but aren't quite in the right lane of sanity... which is a good thing! For the audience, at least.. Just the fact that they took pretty girls and made them stars as goofy and dorky as possible formed a type of humanism with the audience, unlike in other dramas where their actors and they are acting. We see girls with aspirations in their hearts, not a script in their hands.
Let first say I love YoonAh but I'm going to be very unbiased towards my bias. I love how the characters act like humans and it is another P&H duo-tag show. Then the dramatic entry into the show with a guy-vs-friend fight over a girl. They don't really fight but they sort of struggle for power over the love of YoonHee. Then there's a fight of the main guy from YoonHye and her friend. Then everything is screwed up in the end... Or is it? In the future they have kids and I love that they are played by the same characters (talk about looking like your parents) and how there is still a sort of love but then again comes the struggle between them for love and we're back where we started this mess. But everything I love in a drama is here: Music, Love, DRAMA (duh!) and a good twisty-turny plot that keeps you wanting more. If only it was on Netfix!
