Another thing about the Simpsons which I've never been comfortable with (and this has been a problem throughout its run) is that I rarely see a show where the production staff have such a virulent, all-consuming disdain for their fanbase. I know fans can be extremely annoying and irrational sometimes, but I've never seen a show go out of its way to insult and shit on them quite like the Simpsons has.
There was a writer for the show called Ian Maxtone Graham who gave
an interview to the Independent where he dedicated a whole section to bashing fans who criticized the show. He also made some comments about female writers which, had they been made today, would likely have got him thrown off the show due to the Armageddon-like tantrum Tumblr would throw over them. I'm not a radical feminist and even I thought his comments were pretty out of line.
However, that interview occurred around the time of the eighth season when the show was still widely considered to be good. Nowadays this behaviour continues despite the fact it's not just fanatical fans saying the show sucks anymore, it's everyone.
And what's funnier is that the writers claim again and again that they don't care how much people say the show sucks, they don't listen or pay any attention to it... even though they bring it up in multiple episodes, wheel Comic Book Guy out as a strawman of fans whenever the opportunity arises and Matt Groening confessed he felt like "knocking their electronic noggins together" in regards to one newsgroup which criticized the show.
It's never nice to have people criticize you or your work, but the way the Simpsons staff react to criticism just comes off as petty and bitter.
