Im gonna disagree. I think the only reason it hasnt been cancelled is the production deal they have.
The show has poor ratings and isnt being nominated let alone winning awards.
Shows arent being saved by getting good reviews online. They want awards or ratings. Studios aint gonna print seasons 2's rotten tomatoes score and frame it on a wall.
If what you're saying is true "The Wire" wouldn't exist. It's only saving grace was critics loved it. David Simon himself will tell you that.
It won zero awards, wasn't even nominated most of the time, and nobody was watching it back then.
Obviously NBC would prefer it won awards but the press saying it's better than anything on premium cable is huge. It legitimizes NBC to the world.
