Despite all the plot holes and (as I've recognized now that I'm older) poor writing, I would still say I enjoy HP. Huge LotR fan back when I was younger, still a big fan though I've forgotten most of what I've read in the Silmarillion. I enjoy the ASoIaF/GoT books but not the show as much.
Big fan of Marvel, I enjoy DC as well but not as big a fan. I also like One Piece and Star Wars, though only the Old Republic Era. Those are a few right off the top of my head, hbu?
