What can I say? Blades of Glory is Talledega Nights transplanted from the world of NASCAR to the world of figure skating. Given the premise, it's formulaic. I approached it with my best stone face, daring it to make me laugh.
And it did, all the way through. It helped a bit, I think, that I find figure skating to be bizarre, weird, and borderline creepy in the first place. The movie takes that concept and embraces it.
Jon Heder plays a very good straight man to Will Ferrell's usual inspired looniness. The supporting cast is also great: Jenna Fischer, Craig T. Nelson, Amy Poehler, Will Arnett, and William Fichter.
Might not work for you, worked for me.
