I rented the box set of the shield series 2 from extravision. I opened the box that said disc 1 of 4 and watched the first episode. I must admit I was a little lost on some of the plot points and backstory. Also, the ening seemed pretty dramatic for the first episode. I thought maybe the second episode might fill in the gaps but there was no second episode. The disk only had one episode, then it dawned on me….noooooooooooooo..what have I done!
