I was watching several series for a few years, and new ones kept coming up, and I got bogged down. Missed a few episodes, then decided to wait until I could just watch the entire season at once, to catch up, but then fell behind in several more series. Then you would have some series take several breaks, and I wouldn't know when to start watching again. Then you get filler episodes that don't matter, and don't interest me enough to catch up on them. Then add to that the aforementioned fact that a lot of shows I enjoyed got cancelled after I invested time into them (Sarah Connor Chronicles was a huge blow to my enjoyment of TV), and I just stopped caring. I mostly game, exercise, or watch movies or the Marvel shows, on Netflix. I'll watch some occasional cartoons (Family Guy, Simpsons, Archer, etc), that doesn't require too much knowledge of previous shows, but I can't invest time in like 10 different series, that require me to watch each and every week.
