The only book series I have read so far is "Pugad Baboy" which is a comedy comic book. I don't know what your Tagalog speaking level is, but if you're conversational and you like comedy, I think you'll enjoy reading Pugad Baboy.
GMA-7 has a number of Fantasy tv-series, but I haven't watched any of them because I am an ABS-CBN Fan. I can't give you my opinion on those.
FPJ's Ang Probinsyano is a good action-based teleserye. MMK (Maalaala mo Kaya) is also a good ABS-CBN show since each episode is about a real life story of average Filipinos or sometimes celebrities. Those two shows I'd recommend you take a look at.
ABS-CBN has a few other variety shows or talk shows like Magandang Buhay, and other shows that I can't remember the name. I haven't watched them, but I thought I would let you know just in case you wanted to check them out.
ABS-CBN's Youtube Channel has a number of Full Episodes of Past Teleseryes. I do not think all of them are romance-dramas.
The Filipino Channel website has a free plan you can use and you get a number of free Teleseryes, and Movies you can watch, as well as some episodes of comedy shows. That's another thing you might want to check out. They have a good list of movies that aren't all romance-dramas.
