Recently in my viewings of various anime, I came across "Oh! Edo Rocket", a show that borders on the inexplicable, as it's an anime based on a play based on a legend that is loaded with parody elements. I vaguely described it as "Excel Saga with a continuing plot" but it's hard to explain it.
One theme touched on, especially later in the series, is that sometimes things can be inspiring but aren't necessarily "useful" or "even lasting." Sometimes big useless, even stupid stuff is indeed a good thing.
Big, giant, useless, crazy stuff can inspire people.
Stupid blatant nutty things can shock people out of complacency.
Huge insane efforts can help you explore your limits and yourself.
It can also be fun, and we usually need more of that.
