Bloodline is absolutely fantastic, I've been recommending it to all my friends. I can't praise it enough - also glad there's a second season coming in 2016. Apparently the creators (KZK) have a 6-season arc planned...

I'm almost finished with the first season and had to force myself to go to bed at like 1am because I wanted to keep watching more.

It's not quite "Breaking Bad" levels of tension and machination but it's a good, slow burn that really picks up as it moves along. Doesn't hurt that I just got back from my first visit to the Keys right as this came out.
