>>46187262Personality ≠ interesting. There's being entertaining and basic, and there's being interesting. Ash has nothing unique or interesting about him to provide. He fills his role well, most of the time, especially in Indigo, but I think you're the one who's confused about what 'interesting' means.
Brock is interesting. He's a gym leader, he has a troublesome home life that forced him to grow up fast, he has a dream that changes because of his experiences, and despite his maturity, he's still incredibly weak for pretty women. He's multifaceted and interesting. Ash is not. Both good, but only one is interesting. Can I help you understand any other basic definitions, or are we good?
