Explain to me a single positive aspect of the 2 episodes serving as the season 5 premiere? Were they funny, like, at all? Was the story anything but a generic mess relying on ridiculous timeline rules, just to result in it absolutely not mattering at all? Like there were a few decent episodes in season 5, but most of them were mediocre, and some of them were fucking Lemonhope.
Season 6 again, you could point to a new select good episodes but most of them weren't nearly on the level of what was standard in season 1, 2 or 3, or even 4 for that matter. Along with dragging out the narrative surrounding the comet and orgalorg, with pseudo existentialism sprinkled throughout. It's thoroughly pretentious.
Season 7 is the one that started PB's self exile, something so boring and contrived, the details of it are so completely irrelevant that they ignore it for half the episodes they bother to mention it at all, making for some of the worst episodes of the series like Varmints, Neddy, and Yellow Line. The Stakes miniseries being probably the worst of the 3, featuring the most generic villains we've seen in the show, just plain, boring and forgettable vampires in a show that had spent most of it's prior seasons reveling in the most inane and creatively stupid evil creatures. Even the Orgalorg was a more creative enemy. When the vampire king isn't spouting generic "smart" lines, the jokes are falling flat. Marceline's excuse for a character arc here completely fails because we have 6 previous seasons of her absolutely not giving a single fuck about being a vampire, so there's no reason to fucking care if she stops and definitely no reason when she just decides to stay one in the end despite it still being completely possible to go back if they didn't fuck up and let the vampires out this time. The only reason she didn't is because of the status quo (not that I'm complaining)
Also just how much worse the animation got is incredibly noticeable
