I'm gonna have to say that Twilight Princess is my second least favorite Zelda game, slightly above Zelda 2 for NES.
Here's how I'd rank 'em:
Ocarina of Time: 10/10
A Link to the Past: 10/10
Link's Awakening: 10/10 (partly because it was my first Zelda game)
Wind Waker: 10/10
The Legend of Zelda (NES): 9/10
Majora's Mask: 9/10
Twilight Princess: 7/10
Zelda 2, The Adventures of Link: 7/10
Twilight Princess gripes/bitching:
The storyline was boring, the synth music sounded cheesy and dated, the Wind Waker sound-effect scheme didn't match up with the visual style, there was too little original content, the puzzles were too easy (or just stupid, like the one before the Master Sword I mentioned a few posts ago), the bosses were too easy, the side-quests were very unrewarding, and the ending was one huge, shitty anti-climax.
I'm sorry, but considering they worked on this game for about 4 years, this game should've been a whole lot better. There were some cool moments when they referenced Ocarina of Time, but there were some parts where they just flat-out copied Ocarina of Time (like finding the 4 ghosts in the Gerudo prison thingy).
I really can't believe I am writing this, because this is the first time I've ever been disappointed with a Zelda game.
*sigh* I'm gonna go play Wind Waker now.
