I don't hate Cait Sith because everybody hates him, I hate him because he is a horrible character. The only good thing about Cait Sith is his music. In fact, one of the best moments in the game for me was when he was crushed by the black materia. This was followed by one of the worst moments of the game, however, when he had the nerve to rejoin my party just after I thought I had ditched him for good.
