I love Kristoff, if he were real ... I'd be in love, haha!

I think he looks amost perfect. Meaning, he's got normal eyes, like you mention the eyes from the girls are just too big (but that usually happens in 3D movies like this). His nose is maybe still a bit too cartoonish, but the hair and such, it's perfect, haha

I loved the animation during "Let it go". Some movements are so fluent and beautiful.
I love it how she looks at the camera at the end of the song, haha!

I never hated Olaf, I spot a cute character miles away, lolz.
He was a great addition in the movie. I did think he was pure comic relief before I saw the movie (as I didn't knew how and what), which he mainly is though, but when he's alone with Anna at the end of the movie, it's quite emotional.

Yes, I saw the movie ... *ahum* I found it somewhere, haha.
