Frank Hvam vs. Larry David.....
I am a fan of both series and I agree with those who say Klown (the series) occasionally feels like a "Curb" rip-off. However, I think the character of Frank is sweeter and more naive than Larry David's, which gives it a little bit of a different dynamic.
I also think that "Klown" seems to take the subject of sex and dysfunction a little further, and to sicker levels. It seems to take more chances, which could be more due to the less uptight view towards sex in Europe.
All in all, both very solid series.
