So they had this "Greatest TV Characters of the 21st Century" March Madness style poll, and it kind of summarized everything wrong about The Ringer's pop culture mentality. That they have kind of a hive mind mentality and live in a bubble often outside of the public's perception of things. They did the seeding and chose the names based on staff recommendations, so this wasn't just one person's view of things. The seeding is a complete joke; worse than the names chosen. The most obvious is that PWB's character in Fleabag was a #2 seed and faced #15 seed Eric Cartman in the first round.
I haven't seen Fleabag, but I can imagine it is very good, funny show and PWB is great as the main star. That being said, let's take a look at the episode count from the 21st Century:
Fleabag: 12
South Park: 260
So of course in the public voting poll, Cartman upsets Fleabag. Then one of the Ringer staff members in the follow-up article writes about what a travesty this is, and that people were just remembering what they watched when they were 14 and were underselling the brilliance of Fleabag. I guess that is different than just voting for someone you started watching last year and not over the past 20. It was just dumb, and there are a lot of similar examples where shows of the past few years, even smaller niche shows like Fleabag, have multiple entries while wildly popular shows that might be a bit older (Lost, The Wire, etc.) have only one entry. Plus it ignores super-popular shows that maybe don't have the internet critical acclaim but are clearly very popular. Whether you are a fan of the Big Bang Theory, Family Guy or the Walking Dead or not, I think it is fair to say that Sheldon Cooper, Peter Griffin and Rick Grimes are among the 64 most memorable TV characters of the past 20 years.
Zach Lowe on his podcast asked Bill what was up with the tournament and why was Cartman so low, and Bill basically buried the tournament, saying that once he saw there was only one character from The Wire, he was out and it was just something the Ringer kids are doing.
