Let's deal with the characters first. Clichéd? Perhaps. They do fit into some archetypes. But then, they're meant to. The point is to have a group of people working together who complement and clash with each other. But they're not 2D carbon copies of archetypes either. Tidus is a whiny douchebag? Okay, but he's also got severe childhood issues with his father and mother. Plus, he stands up to
everything when he decides that the woman he loves isn't going to die. What about Tidus being the egomaniac sports star? Again, he's got a bunch of insecurities because he's always living in his father's shadow. Then he gets transported to a completely different world and is
still living in his father's shadow, only this time his father is a giant smurfing whale monster who is hell bent on destroying everything. Then he has to come to terms with his own mortality, a complete existential crisis because
he's not even real and does it all while still maintaining his flaws; that is, he's still a fish out of water and completely clueless on how to act in Spira.
