Yeah, the whole "Disney is laughing in the face of their previous quick marriages trope!" is completely undermined by the fact that Kristoff and Ana fall in love in a few days time. Maybe instead of kissing her he could've asked her out on a date to show--hey! It's okay to take things one step at a time. You guys went from disliking each other, to being friends, to having a crush.

Also, I know it's sisterly love verses mother-daughter love, but Disney did the "family love is true love too" much better with Brave, imo.
