I really recommend My Husband’s Lover. I think it’s the only BL drama shown in TV cos Filipino society are still somewhat conservative so it’s very rare. Its full eps are available in Youtube but sadly, there are no English subs.
Amaya - fantasy historical drama starring Marian Rivera. I don't think there is anything like it out there. It was also a big hit in other countries like Cambodia
Honestly though, the last Filipino drama (come to think of it, I think it was the only one...) I have seen from start to finish was Saan Ka Man Naroroon (Wherever You Are) when it was on air. LOL!
After that medical school and work intervened so I would see a few episodes of an airing teleserye here and there. My household (and the other household I boarded in for a year) does not watch GMA dramas at all, just those airing on the rival station ABS-CBN. I'm thinking of picking up Amaya one of these days though.
