2x with skipping is the only way I can watch many “seminal” animes. Most of the time, due to cost saving measures taken while doing the animation, you’re not really missing anything by going fast.
As for the skipping, well, all I have to do to justify it is point at the “heavy breathing” scenes in Dragon Ball Z and even the most hardcore fans will forgive me.
If you really want to know how it ends, look up a sunmary or watch it at 2x speed with liberal skipping.
Skimming technical books is also severely underrated.
