Saw the first two seasons, not bad at all. At first glance, I thought it was just another boring show but since it was by Netflix (they usually produce quality stuff) I thought I'd give it a shot and I wasn't disappointed Need to catch up and watch the third season now
I've only seen half of the third season since this time I'm watching it together with my friend, but so far it's not bad. I like that they use each episode to show the background story of each character. Piper is really starting to annoy me, though.
