I remember watching the Runaway Guys do a let's play of Star Fox 64, where Emile was ostensibly playing the game for the first time. In order to speed along the process, Jon and Tim played the routes up to the levels he hadn't gotten to yet, without him having to play all the stages along the route, like you're supposed to. As such, when he got to the boss of Area 6, the penultimate boss of the hard route, he got his chassis kicked. Immediately, he complained that the boss was badly designed.

And I was just thinking "My guy. You have skipped over the majority of the gameplay you're expected to have done to reach this point. YOU are badly designed!"
