Hyperbole aside, I can understand where this guy is coming from. I've played through and beaten pretty much every Zelda game, I'm still working my way through the Hard Mode for the original NES game.
I will tell you right now, the only game I enjoyed more than Twilight Princess was Majora's Mask. The storyline is incredible, the controls are fantastic, the mood and puzzles are great.
However, the replay value for Twilight Princess is terrible. What it really needed was some sliding AI so you could go back through with tougher enemies. The only enemy in the entire game that gave me any trouble at all was the Knight, and as soon as I figured out the pattern he became just as easy as everything else.
Along with this, the explore-everywhere-even-if-it-means-getting-in-way-over-your-head aspect that made the original NES game so much fun was totally gone from Twilight Princess. There was never any reason to go back to an area you had already explored and you could never get to a place before the story called for you getting there.
The linearity of the game wasn't an issue the first time I played it cause the story was simply that totally awesome. I beat the game in a week.
the second time through I began to realize that there just wasn't much room to play around with things, and it got very boring very quickly.
It's a good game, excellent story, certainly not an utter failure and complete disappointment, but yes, I can understand the tedium of having to play through a second time.
