At its best, this show is riveting and emotional. At its worst, we've had things like the finale with Irene Jakob. This latest off the map detour at least has relevancy in terms of seeing all of Allison's self-absorption repeated in Joanie. If we really needed that. But otherwise it's so off point as to be ridiculous--not to mention that it's environmental hysteria at its worst. Also? Has there been a single other episode with only one viewpoint? What a freaking waste.
