I thoroughly enjoyed this movie. It is in the same line as other Will Ferrell classics like Anchorman, Talladega Nights, or Blades of Glory. The musical numbers, even with the comical mishaps, were goosebumps-causing.
The acting was spot on for the type of movie (An comedy as opposed to a drama or suspense film). I thought the movie was a lot funnier than it appeared. Will and Amy, cause we're good friends, had an amazing chemistry and really sold me as Icelanders.
If you are looking for some solid musical numbers, a good country mouse finds fame story and some Will Ferrell style laughs, this is the movie for you.
Oh and the actors that played the Icelandic Counsel (I don't remember the official title), as a group were hilarious. Especially the short blond lady.
