Any popular film can be considered overrated.
Is it a typical princess story? No. It isn't. The film is rooted in the familial love of two sisters. I have yet to see a film with such strong female leads where the plot is not centered around a man. That alone makes it ASTOUNDING! The prince was peripheral and Kristoff was basically along for the ride. Of course Sven and Olaf were popped into the story to lighten it up and to give kids something to grab onto. Not only does it pass the Bechdel Test, the fact that the film grossed $1,272,346,009 worldwide sends a signal to the entertainment industry that mainstream films don't have to be tailored to teenage boys. Overrated? That's an incorrect prism to view this film's success.
The story has its spotty bits and plot holes. And the musical element kind of ends half-way through. That was strange. There seems to have been a lot of reshaping while they were making the movie, but it's still quite enjoyable. Much more so than the snoozefests of Brave or Cars 2 or, dare I say, Monsters University. I think everyone had higher expectations for Monsters U, but they just played to the kids the whole time. It wasn't bad. It just wasn't anything special. Well, aside from that sly ending.
As for Frozen's songs, I enjoyed Let it Go, Love is an Open Door and In Summer. Those three are quite strong. Apparently strong enough to inspire a Broadway musical adaptation.
So, overrated? Sure. What entertainment property or entertainer really deserves that kind of money and fame? None in my opinion. I'm just happy that, if it had to happen, it happened to a film like this. Great story, wonderful characters and an empowering, progressive theme.
My RT review from last year: A solid contribution to Disney film history. It also passes the Bechdel Test with flying colors. I just wish they'd discard the waifish waistlines in favor of creating some realistic or full figured heroines for once. 4 out of 5 stars
