No, it is not porn.
If you enjoy a new take on norse mythology, this may be a show to try out.
An explanation of the show taken from IMDB:
It is currently airing it's second season in New Zealand and I believe the first season has also aired in Aus and the UK. It's a pretty great show once you get into it.The Almighty Johnsons is a new South Pacific Pictures comedy-drama series about four brothers, raised in heartland New Zealand, who also happen to be the living incarnations of Norse Gods. They even have their own super-God-powers. Sort of - it's just that their powers aren't actually all that powerful.
Here's the trailer for the first season to give you a taste of what it's like.
