Best TV show to learn norwegian? (Oslo)

Hi Everyone!

I am looking for a good tv show to watch in order to get more familiarized with the norwegian language.

For example, most of my english is because "How I met your mother":

- at first I watched with spanish subtitles (my native tongue)
- then with english subs
- then no subtitles at all

I would like to do the same with norwegian, due if I know some norwegian, it's very difficult to me understand what norwegians say, even if they are talking using words I already know.

Thank you!
