Just finished S9 -- loved it. I won't offer any spoilers, but there is some outlandish stuff -- and S8 was more bawdy than previous seasons as well! Seems doing the Swearnet movie really loosed up the boys' funny boner.
Great directions for the characters this season -- new villains, new authority figures, awesome Jim Lahey arc with a heartbreaking performance toward the end of the season.
Great directing by Torrens and others this season -- the park looks great!
Lots of that Platonium love shit with the boys too, and between the other characters -- that's the heart of TPB, and it's as great here as in any of the previous seasons. Unlike some other new sitcoms, this season ends as strong as it began, something the boys have become really good at. For a show that started off resisting the idea of season-long story arcs, it's become one of the best examples of that sitcom ethos.
So, is there any news on subsequent seasons? I'd rather have more of the series than more movies!
