First seasons was great. Second season started strong but dragged. Im only on the 2nd episode of the third season and its getting harder go watch. Long drawn out scenes which add nothing to suspense or story. The time wasted with these scenes totally robs the story of any sort of gripping moods. I actually found myself skipping forward to get to dialogue. It all seems a bit lost.
Edit: although the series to drag itself out as previously stated. When thing's come to unfold nearer the middle of season 3, the story redeems itself greatly.
