Too many good characters vs too few worthy villains :( Would have been nice if the Tendoshu weren't so badly trolled by Utsuro. All of that build up throughout the series was for nothing.
Sucks that Ane and Mone were totally forgotten until now. Ane has one of the billion hilarious lines in Gintama:
"If he touches your left (butt) cheek, let him touch your right! Everyone knows that you're supposed to turn the other cheek!"
