The only TV show I'm currently following is the 2014 adaptation of Fate/Stay Night. Unfortunately, it's currently only on TV in Japan, so those of us who live anywhere else have to catch it on Crunchyroll or Hulu. And really, the only reason I'm even watching it at all is because it's being animated by ufotable, who were behind the amazing Fate/Zero. And as a result, the story is pretty mediocre (it IS Fate/Stay Night, after all), but the animation is often breathtaking.

Now, as for favorite TV shows of all time, I counted my 10 favorite anime on my profile page, but I didn't do such a thing for other TV shows, so this'll have to be where I do that.
Top 10 TV Shows:
1. Daria - Used to air on MTV and Noggin/The-N. This is, by far, my favorite non-anime TV show of all time. Excellent writing, great balance of humor and drama, and truly memorable characters. This show has probably been one of the most influential in my life.
2. Futurama - Used to air on Fox and Comedy Central. I never REALLY got into The Simpsons (born too late, most likely), but Futurama was right up my alley. Great stuff.
3. Penn & Teller: Bullsh*t! - Used to air on Showtime. If there's anything I love more than learning new things, it's learning new things while being entertained. Always funny and enlightening, even if I ended up not agreeing with the viewpoints presented.
4-7. The Naked Archaeologist/Engineering an Empire/Decoding the Past/Ancient Discoveries - Used to air on History Channel. It's archaeology, history, and mysteries. 'Nuff said.
8. The Universe - Used to air on History Channel. It's space. 'Nuff said.
9. Avatar: The Last Airbender - Used to air on Nickelodeon. You really don't see high-quality action cartoons like this anymore (well, outside of Japan, anyway). The characters were likable, the setting was immense and interesting, and I loved how complex the story and morals were while still being appropriate for all ages. Excellent series.
10. Family Guy - Airs on numerous networks. Really only counting the first few seasons here, which were comedy classics. If the series stayed cancelled after season three, this show would be way, way higher on the list.
