I am a Norwegian girl who really love Bones!
When I found out that Bones was airing an episode based on a body found on an Norwegian Black Metal concert, I admit I was a little scared. Normally when American TV shows mention Norway, it all goes wrong. I remember the X-Files': Død Kalm, where the Norwegian language was poor and sounded a lot like a Finnish immigrant living in Norway. Seriously! And the dudes name was Trondheim! That is not a normal Norwegian name. If you believe that, you probably believe that there are polar bears wandering around the streets of Oslo (our capital town, if you wondered ;P) A common name for a Norwegian is Olsen or Jensen, or Larsen.
Though the Norwegian "Dr. Brennan" sounded more Swedish than Norwegian, the language was better that expected! Especially the police guy at the beginning of the episode.
Norwegian black metal is one of the things Norway is famous for. But how they managed to mix up Norwegian black metal with black metal and death metal, I really don't know. That was poor research! But the episode was saved because of Gordon Gordon, the confessions of Brennan, Booths reaction to her confessions and sweets and his background and reason for being so clingy. All in all, I really loved it! But then again, I love all Bones episodes...
