How important is difficulty level in a Zelda game to you?

Many people seem to highly prioritize Zelda games/video games in general for their difficulty level, most wanting a challenge, with Twilight Princess for example seeming to be harshly criticized by a lot of people for being "too easy", with people seeming to be put off it for this reason alone. To me though, difficulty level shouldn't be the only reason or even main reason you play a game, particularly a Zelda game. I think boss battles for example can still be really fun and epic without being very challenging. It's not like the Zelda series is even known for being particularly challenging, except for the first two games of course. How about you, how important is difficulty level in a Zelda game to you?
