Sections or parts in games people tend to find frustrating that you actually enjoy.

Down the tubes level in earthworm Jim I've memorized all the levels and actually the race against time in the submarine is a piece of cake for me.

Outrageously hench answer.
Mine would be Test Your Might in Mortal Kombat, or really any sequence that involves button mashing.

The Catacombs is probably my favorite area in Dark Souls.

I recall people being real mad at the incredibly slow build-up of the original Half-Life (from the tram to the disaster at the test chamber), but I honestly think it's examplary gameplay. They convey so much just by letting you walk around NPCs doing their own thing and interacting with the environment with very little dialog to boot. Unlike the vast majority of games, this one's world is not about you -- you are simply another face on a huge company and the game isn't afraid to let itself breathe before dumping you into endless action from then on. It's economic storytelling at its finest.
