The top rated shows are all objectively good for what they are though, they aren't really any glaring impostors. Literally every TV show on IMDB over 9.0 is a certified banger. Just really surprising to see it rated so highly, especially as all the other dexter spinoffs and comeback shows haven't had good user ratings. Guess the only way to know is for me to watch it, but im so sick of dexter lol
It's definitely been something that affects more recent releases because they've done something to the calculation algorithm.
Filter those results for the last five years. I've also noticed a lot of foreign language shows are filling the 9+ IMDB ratings too. They don't have many votes when you actually look at the totals but they're all giving 10/10 because people are only arsed to vote if they feel strongly these days, if it was just OK people move on and don't bother but the people who love it give them all 10/10.
The survivor bias is real though, as you said you don't even know if you can be arsed with it. Anyone who watches it now has already stuck with a load of mediocre to crap telly and they're invested.
