While it's a very unique film full of appreciated refreshing elements from what Disney usually does I, also a childless adult Disney fan nor my mother understand the hype either. The animation is beautiful, the soundtrack wonderful and the depth of the story's intended direction is reaching but the plot is very flawed in ways which bug me.
I'd personally found the characters to be underdeveloped and there is a pretty significant plot flaw that I picked up upon my first watch in the theater.
The film is lacking in backstory and connection between some elements.
To have this one character be the only one with special abilities is a key element that needed to be explained. Unless she'd actually been cursed in infancy and the father not wanting to shame her further fibbed to the troll when he answered the question that she was born with it. It would certainly make more sense that way.
Further more that ritual which took Anna's memory of her sister's ability was a significant occurrence which connected the three protagonists (the sisters and Kristoff). There were at least five stepping stone occurrences which begged for a revelation of that ritual:
*The beginning of the sisters' adulthood when Anna got upset at Elsa for always shutting her out.
*When Elsa's powers are revealed to the entire kingdom and Anna tells Hans upon his questioning it that she didn't know.
*Hans asks about the white lock in Anna's hair and she answers that she was born with it.
*Kristoff telling Anna that he'd once seen his troll family perform a healing (which was her's).
*Anna remembering Olaf from her childhood.
I'd waited for all these jigsawed events to come together but they never did. These things bug me even though I do enjoy the film, I even have the blu-ray combo.
For my mother Olaf is the only reason worth watching it.
So I wouldn't call this one of Disney's most well done films and thus do feel it somewhat overrated. I can name several Disney films which are far better developed such as
Tangled,
Brave,
Princess and the Frog and
Meet the Robinsons(and the
Meet the Robinsons trailer was a huge turn off for me but as with most I can say the same about, it surprised me).
For me it doesn't have a proper villain
I've got to disagree. Actually I believe a number of the most recent Disney villains have returned to being three dimensional as back in the days of
Lion King and
The Little Mermaid. I found that making the prince the villain by itself let alone his subtly to be not only brilliant but realistic.
