What to do, What to do....
With so many bad television shows, this choice will be a difficult one. I suppose it should be limited to currently running shows, which eliminates _Scooby Do_ and _Fraiser_. It should also be a show that is not just stupid and silly, but also a program that does actual harm to the viewer's mind.
A good choice would be any of the shows that deal with "ghosts." Certainly _Ghost Hunters_ on the Sci-Fi Channel would top the list, as would _The Ghost Whisperer_ (and any other show with the word "Whisperer" in the title).
But the absolute worst show on TV would have to be _Medium_ on NBC. The main character is played by actress Patricia Arquette as the ghost-whispering medium. Frankly, so much of this show offends me that it's hard to know where to start.
First, the medium's husband Joe Dubois, played by actor Jake Weber (a competent actor, which makes it hard to explain why he took this gig) has a tone of voice, when he speaks to his wife, that is grating and annoying to listen to. If anyone were to use that tone of voice with me, I'd punch him in the nose. How does "the medium" stand listening to this? Doesn't her alleged "6th sense" tell her that her husband is a jerk and that he talks to her like she's an idiot (not that she isn't an idiot-- but it shouldn't be thrown in her face that way). If she really had extra-sensory perception she would read his mind and dumped him a long time ago.
The same thing goes for her funny-looking kids (and especially the chubby-faced daughter). If "Allison" really had an ability at all to see into the future, then she would have avoided having kids. Or, at least, she would have begged off having marital relations with her husband on the night this kid was conceived. If she was really psychic, she would have seen just how funny-looking her kid would be in the future.
I could go on, but why? This show is a big-time stinker.
