It's a real culmination of the series moment. Not an endgame feel, but a touch on elements the series has been building up to. You've got: a serious, serious look into Gintoki's character with a bit of backstory fleshing, an all out battle with CONSTANT rises and twists to excellent, excellent pacing; one that even ends on a note that's a first for the series, and more tsuki/gin shipping fuel, which just makes everything better.
This one is actually pretty different. Definitely the most personal of arcs we've had in a long time, which is a shocker given the troll way it started.
