What's With The Season 4 Disconnect?

I HAVE NOT WATCHED THE SHOW YET SO PLEASE NO SPOILERS

I'm looking shows to watch once I finish my current Sopranos rewatch so I was on the SeriesGraph website to look up shows. Ever since Game of Thrones I've been unwilling to invest time in a show that's currently airing out of fear that it'll end like shit, ruin everything, and waste my time. Anyway I've always heard True Detective had an incredible 1st season and that the 4th season was the next best one. Critics praised S4 almost to the extent of S1. However the IMDb user scores for season 4 are trash, like GOT Season 8 levels of bad. I find I usually agree with critics more than audiences but I was wondering why that disconnect exists in the first place.
