I don't understand what people have against Usopp. I know a lot of people who think he should be burned in effigy because he's "a coward." I think thae fact that he is scared shitless, but still manages to kick ass once in a while (okay, after a lot of screaming like a girl and running around) makes him that much cooler.
I never liked Robin partly because she just doesn't seem to serve much of a purpose. What does the crew need an archeologist for anyway? That and she doesn't seem to fit in that well with the rest of the crew. She's too serious. She's an okay character, but if Oda was getting rid of someone, I have to think of the old "last hired, first fired" rule and think of her.
