I watched MEDIUM first when I got in from lunch (while also fielding two lengthy phone calls). Loved the show, but I, too, guessed who Debra was before the reveal so it wasn't a surprise. I did, however, feel sorry for poor naive Allison for putting all her trust in this friendly stranger.
I really loved the DEAL OR NO DEAL sequence.
I don't mind the story arcs when the story necessitates them. We've also got Joe's agonizing decision about Diotech going on at the same time.
But there haven't been THAT many MEDIUM stories that couldn't be self-contained.
I have to say that there was a ratings drop last week, and if there was one last night, they may not try any more of these lengthy story arcs next season.
