I've actually caught a few episodes of Big Bang Theory since 2012, but put off checking it out because I didn't realize that it would actually be my cup of tea. I liked it a lot more than I ever expected myself to.
Aside from that, I've been on a Daria kick lately. I haven't watched that show in at least 12 to 13 years, and I appreciate it and understand it a lot more now than when I was in middle school and high school. I'm even still a bit surprised that I've also put off getting the DVDs as I thought that they'd never come out. The same also goes for Rocko's Modern Life. I took a break from watching that show too, but I had a huge nostalgic kick on that show back in 2010-2011.
