I thought all seasons up until the last one were fantastic. The last wasn't even that bad, just how quickly the end was wrapped up in a couple of episodes. They could have made another season out of it. Worth a watch I reckon.
bro i was a skeptic for YEARS due to how long and intimidating (no homo) the show is, and also for that same reason you mentioned with season 8 being so negatively received. Im about half way through it, and I definitely recommend watching. Ive been glued to my tv because of it.
