>>213633035s1: great, even though its main plot hook gets ditched early on and is a sign of things to come
s2: great but jumps the shark, shows off all the ways the show will fuck up in the future with constant plot fuckery
s3: comfy and still sort of grounded, great ending
s4: shit ramps up, it's still great
s5: perfect, and a fitting end to the series if you ignore the final scene of the final episode
s6: stitched together dogshit that goes nowhere except for the finale
s7: perfect and the boys are with their backs against the wall again with everything good about the show dialed up to 11, the end would have been 10/10 if they didn't have the stupid cliffhanger, literally could have left the season as it was
s8: snoozefest that goes nowhere except for the finale
s9: ok, with an awesome ending that doesn't go anywhere
s10: fucking stupid
s11: absolutely amazing, could have been a great end for the show if the ending wasn't so absolutely shit
s12: i and many others have lost interest
in any case, the filler episodes are always very good across all seasons. the main plot is arguably worse for the show's health than the padding out of seasons when the writers get to flex their creativity
