Why cancelled?

I'm going to disagree vehemently with that assessment of this crap fest.
check my other posting here for my reasons.

I thought it was excellent myself. I prefer the Danish original, but this version had its own strengths. Linden and Holder made it great.

It got cancelled twice in the US.

Kinneman seems to have gone on a major steroid regimen, the guy is is huge. When he started this show he was a scrawny kid, now he's kind of creepy looking. I would not want to see another season of this show, though I did enjoy the first seasons.
