This is more of a question than a forum, but I LOVE THEM!!!! Kristoff is stocky, and isn't your typical "dashing prince" type, but I love him all the same. He is very handsome in my opinion.
Anna and Rapunzel, in my opinion, don't look too similar.
AND ELSA OH MY GOD DIES I LOVE HER SHE IS ABSOLUTELY GORGEOUS WOW JUST WOAH
I confess I prefer the early, hand-drawn concept art for the Snow Queen, Gerda/Anna, and a boy I'm guessing is Kay/Kristoff before they changed it to CGI "Frozen." (Just run a Google Image search of "Disney The Snow Queen" and you'll see.) I guess their final designs are nice, but I actually don't like the way CGI looks or moves. I find moving 3D people vaguely unsettling, like living dolls.
