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.
