You make several good points. The formula of their show is getting a little old - the carefully spaced dreams that each tell a little more so the fact that the previous one wasn't 100% accurate -- I think I would phrase your point a little differently: even though she knows she's not always right, she always wants others to act definitively as if her current interpretation is correct.

In actuality, the other (evil) woman's point - a 50% correct ratio in prophetic dreams is pretty darn good.
Apparently it just isn't dramatic enough to sustain the show.

On a possibly unrelated point: based on your other reader's reaction, I may have jumped the gun in deciding not to watch the last hour. Oh well - I already like Joe.
