Episodes 1-3 were absolutely masterpieces
Episode 4 was still fucking great but in retrospect clearly transitional
Episode 5 was actually rough as fuck and should have been a warning sign, Scotsman scenes notwithstanding which were fantastic as always
Episode 6 was pure fanservice that could have been a bit better, but also resulted in the removal of the ghost samurai that everyone was hyped about, good but not great
7 and 8 were both fun if a little bit rushed, particularly episode 7, but were still actually pretty enjoyable
9 was actually a really fucking solid episode and the ending was the most hyped I'd seen this board in years
10 was a clusterfuck, they dropped the ball here. Everything that can be said has been said but holy shit I wish they had just one more episode to work with here, or at least an extended-length episode.
Overall the season was good to great, with some high and low points, none of which were especially bad and some of which were some of the best TV animation we'd seen in years. Until we reached the last episode. The last episode overshadows the whole fucking affair, and even going through each episode makes me feel like the season almost wasn't worth it. I really wish that the series had been a little longer, say 12 or 13 episodes.
