I used to watch those shows only occasionally. And only one or two at the time. I didn't get that many series watched. But at least I didn't spend too much time on them either.
They started to pile up. I had to weed out shows from my watchlist and curate the shows I watched carefully. Until I finally got the list down enough and had some extra time to watch them all.
But that just opened the floodgates. Now that i had watched all the shows I wanted I could pick a new one. Or two. Or ten. All the shows I had skipped earlier. All the new seasons of those I had watched. And all those new ones just getting started.
So now I'm following four shows. Fifth one just got another season today. And there is at least three other series with new seasons coming up before summer.
Luckily (unfortunately) one of those has only one episode left for this season. If I can just get all those watched I'd be free again. But there is so much to see. At least they don't do those 24 episode seasons these days anymore.
