Topic: Why all the hate about hard difficulty on games?

Back in 2004 I got stuck in Starfox Adventures trying to complete the test of fear, which involved concentrating to keep a line within a green bar and ignoring everything else that was occurring on the screen. My friends and I tried several times but could not accomplish it and I decided to sell the game to end my frustration.
Recently I bought the game again (after 5 years) for $7 at Gamestop to try and beat the test of fear and accomplished it within five tries. In three hours I had finished the whole game, which was disappointing because I had gathered half of the Krozoa Spirits. I expected longer game play or at least a challenge in the last two tests.
