I mean, it's just good fun.

But it's a lot of good fun. The gags are hilarious, Mash is hilarious and as the ensemble fills out they're all fun together. The action is great - the spread of Mash rearranging a guy's organs with a punch is brilliantly impactful. Lots of little places where Komoto flips a switch  to flex his art skills and shift the tone entirely.

Fantastic series. Always love it.
