Take aside the very important fact that this show is absolutely ignorant over transgenders/transexuals and lowering your expectations towards a very coherent story, this series is really fun. The acting is good, the scenarios are extremely beautiful and dreamy, and even some futile but still somewhat relevant aspects like the level of beauty of the cast, which is very high in comparison, all of this help you get into the universe of GMA.
The screenwriting is obviously the weakest link, the dialogues are pretty much okay, but be careful expecting something you should not. The story is deliberately dreamy and unrealistic, and you have to remember that every episode. Anyhow, the relationships feel very real and you might get caught rooting even for the supposed villains (Sean deserved better).
