Most of the series I'm actually following right now are anime, which I'm streaming over CtHulhu. I hardly ever watch actual TV nowadays, save for randomly catching something on TV due to boredom. On TV, the shows I tend to watch most often are the Big Bang Theory, Family Guy or the Simpsons, or Spongebob Squarepants, and maybe the occasional Teen Titans Go (which pales in comparison to the original animated series IMO because Puffy AmiYumi FTW). But I watch all of those completely out of order, and there are a few episodes I end up watching multiple times because of reruns (happens with Big Bang Theory especially). Though not having cable in my apartment this year has contributed a lot to this.
As for the anime I've been watching, it's quite a list (all of which I have been watching in order), and I've been kind of slowly following all of them. Currently that list consists of Slayers, One Piece, Death Note, Ouran High School Host Club, Hellsing, Excel Saga, Inuyasha, Fairy Tail, Sword Art Online, and Rozen Maiden. Quite a variety, eh?
AND on top of that, I've been following even more anime series at my school's anime club. Since the club is full of crazy people, we've been watching THREE series: Danganronpa, Demon Detective Neuro, and Good Luck Girl. All of which I've found very interesting (there's even a character from the first one in my signature banner) and enjoyed following so far. We have been watching a fourth (Kill la Kill), but we recently finished it and I haven't usually been sticking around in the club meetings long enough to watch it anyway.
