I actually think that this won't get a second season. BUT I do think there will be a Heroes for Hire tv season at some point, like a true detective show with Luke and Danny investigating a weird case that keeps crossing the path of Jessica Jones.
It is funny you mention the JJ issue, I have several non-comic friends and family who loved Daredevil but hated JJ. In fact, I just had this discussion with my sister-in-law about this subject today. I know several people here on the boards have raved about it, but how many non-comic fans liked that series? My sister-in-law just said it was dark and none of the characters were likable.
I haven't watched it yet and so far I'm being told it was not good. I never read the comic, only have a passing familiarity with Daredevil when he crossed over with other MU heroes, and I did enjoy the first 5 or 6 episodes of Daredevil (another series I have yet to finish.) Is JJ a series I will enjoy?
If you don't like dark, skip it. It isn't a "happy" story. I personally liked it but I like all good material whether it be lighthearted, middle of the road, or ultra violent. The villain in the TV show was much better than the same guy in the comic and I really liked how bad he was in the book. Everybody that has mentioned it to me had mostly positive things to say. These boards are the only place I've seen negatives.
Rotten Tomatoes reviews are very high

As are IMDB

If you already have netflix, it won't cost anything to give it a try.
Merry Christmas
Agreed... Everyone outside of these boards loved it. Including my wife who doesn't care for anything comic related.
