Been pondering this for many weeks too.
Take your pick from any combination of -
Covid & no crowds
Rules (I've hated the stand farce). I can't accept rule changes without having been trialed in VFL, SANFL, WAFL. It's guesswork.
Umpiring - both the overall standard and the different treatment of Richmond
Injuries to key Richmond players and a lack of cohesiveness
MRO/Tribunal and the either lack of consistency or what sometimes looks like blatant favoritism
Media - I stopped watching footy programs a couple of years back and hardly listen to the likes of SEN or 3AW anymore. They all have a vested interest in staying on the right side of Head Office so will rarely call out the AFL over stuff
I'm sure the poor season by the Tigers is a part of it for me but the standard of games has been very hard to watch. I have always watched 4 - 6 games per round (even during Tigers poor seasons). I'd be lucky to watch one or two quarters of other games this year.
