The good TV shows might still exist. Last I enjoyed was Better Call Saul but it seems that the "shovelware" concept has reached TV. I saw a few episodes of those Netflix super hero shows. They are not bad just nothing special to keep watching. I guess if there was a lot less tv shows then more attention could be paid to them.
In retrospect, I saw few episodes of the tv phenomena series Buffy The Vampire Slayer. Honestly in today's standards its pretty meh , but I really can see how pre-internet days this was an extremely interesting show. I guess quality+interest is relative.
