Master Roshi having ultra instinct is nonsense, but if we're being frank, the power scaling in Dragon Ball Super is complete nonsense as well. So it's hardly that egregious in a magical cartoon world that can't even stick to its own rules.
Even as someone who shits on powerlevels every time I have the occasion to do so, this is just too much.
When DragonBall usually throws power scaling out of the window it's in order to have a much more dramatic moment. This falls flat here, since it's not dramatic, it's head-scratching.
Ultra Instinct is supposed to be a thing that even the most powerful and most experienced deities of the galaxy weren't able to do properly, and now you're telling me that the old dude who spend more than a third of his extended lifespan to perv on woman is on the same level?
Yeah, powerlevels aside, this is BS.
I get the idea of having Roshi understand the concept of it and even trying to apply it. But to actually pull it off against Jiren of all people is just too much. If it was someone weaker it would lessen the blow, but we're talking about someone who could easily defeat a man who uses time for fighting.
That's just too much of a stretch.
