Back in 2009, I got really 'into' television. It's not that I hadn't watched TV before that time; it's that I learned a whole new way to understand what I was watching. This was all thanks to LOST, which went above and beyond what I normally would have expected of network TV at the time, namely rote procedural action. LOST taught me that TV can do strong serialization and nuanced character arcs in a way that movies just can't. Combined with strong acting, writing, and fantastic music (leitmotifs!), it changed everything about how I engaged with television. After watching LOST, TV became art for me, and I even briefly wrote about it over at SpoilerTV: https://tinyurl.com/y942u297
Today, I am an active TV watcher - both in the sense that I watch as much TV as I can possibly manage and that I try to watch TV with an eye to analysis and criticism. I focus a lot on A) the art of TV production (e.g., directorial or writing choices); B) thematic and symbolic analysis; and 3) social and cultural criticism (e.g., concerns about poorly represented minorities). I think TV has the power to effect powerful social change, through 1) artistry and 2) the telling of unfamiliar stories that can help us bridge our differences.
I used to watch a lot of mediocre television, partly because I did not know any better, and partly because you can learn a lot from mistakes (i.e., well-made TV can seem 'effortless', while poorly made TV reveals a lot about the actual effort that goes into its creation). I'm done with that now, mostly due to a lack of time, except in the cases of legacy shows (i.e., I don't think The Big Bang Theory has anything new or interesting to tell me, or that it's even a particularly good show, but I'm 9 seasons deep, and somewhat invested, so let's finish it up).
Basically, I think TV is the best :).
