Ultimately it depends on how much time you have and whether you want to risk wasting your time or not. Sometimes people might just want to watch stuff that people meme off of or experience a show and learn why it doesn't work. Or form an opinion for yourself so it's easier to join into conversations. Etcetera.
Same reason why I might tell people to watch The Room if they ask even though it's an objectively terrible movie.
If you elect to watch something else, I wouldn't complain lol
I guess there's certain things I will watch based on the hype and popularity, but only once I feel like the initial glow has tapered off. Like one punch man.
I don't want all that biased I read online on reviews and stuff to get in the way of me enjoying the viewing experience in a fair way.
Sorta like how I waited a year or so to get into game of thrones, and I'm glad I did because if I had watched it with my expectations set to elite level I woulda been a bit let down at parts. But since I watched it with a neutral mind set, not expecting a flawless product, I enjoyed it that much more.
And I enjoy things more sincerely that way as well.
