Same with e.g. the Souls games, whose bosses are often designed to be visually and audibly overwhelming when you first encounter them. But after a while, when you get better, come back to a fight later, or watch someone else playing, you'll see it very differently from playing yourself, to the point where a lot of things just feel painfully slow and/or clearly telegraphed.

Doesn't make it much easier though as the window for when you should hit that dodge button is still narrow.
