I HATE both of them and it was really hard to choose which one I hate less. On the one hand, Merida's character development was done better than Naveen's. But on the other hand, Merida before her character development was FAAAAAAAAAAAR WORSE and is even downright despicable!

Naveen, I found funny and at least mildly entertaining. He also never struck me as being as mean spirited as Merida; more of a lazy, self obsessed, jerk; but not the type who would actually hurt someone.

I Actually like Naveen!! XD I thought he was fun! He did need that total kick in the balls though to get him in gear and on the strait n' narrow. He WAS VERY licentious (hehe Sims Medieval anyone?) and maybe a bit spoiled but not as bad as Merida. At least his character development wasn't forced and stupid.
I don't hate Merida but she does PISS ME OFF TO NO END!! "I'M SHOOTIN FER MA OWN HAND" INDEED!! Uhhhg... Tryin WAAAAY too hard for "gurl-power" if you ask me!
Got to giver her credit for being the FIRST FEMALE PIXAR PROTAGANIST!!!

Funny, they're both my 2nd favorite characters in their movies. Cool. Anyway, I love them both! Merida is basically me, and Naveen is such a funny character.

love vs strong dislike

I don't like Naveen.

Not keen on Naveen. And Merida...well, I like her, but boy, I DON'T love her. Not after what she did...
