I was going to write a long reply until I came to this part...

He's not a suitable protagonist for an RPG, he's barely a suitable protagonist for a saturday morning cartoon... or a pornographic movie. He belongs with the support cast and his doses should be minimal
...and realized the folly. Obviously I can justify them - and obviously I can't do any more than that. You're bothered by Tidus' attitude - I'm not. I always try to see the reason and purpose behind someone's actions, both real people and RPG characters, and as such, I had no problem with Tidus. Characters/People don't always have to be badass, be positive, be able to pull through any situation without going down, understand everything instantly, etc. And over the course of the game, Tidus matures a lot as he begins to understand and feel for the people of Spira.

One thing though. I feel that Tidus, on a protagonist level, does his job very, very well. The world of Spira is expansive, complicated and has various cultures, precepts, customs and the like. And all of it must somehow be conveyed to the player. Enter Tidus, someone just like the player, who has no idea of anything about Spira. Through him, we get to see all sides of Spira. NPCs explain things to him, and as such, to us. And just like the player, Tidus develops some "outsider-perspectives": Are the Al Bhed really bad people? Should the teachings of Yevon really be as highly regarded as they are? All these kinds of questions that a Spiran normally wouldn't ever think about (see Tidus and Yuna's conversation on Mi'ihen Highroad). All the while still not being a blank slate, but his own personality with his own backstory and impressions. Even if most of the storyline isn't centered around him, he does a wonderful job as a protagonist. That is Tidus.
