Murder, She Wrote.

I've found lately that I have several issues with this program. I'm aware that I'm approachiung this topic about 15 years after it's window of relevance, but it's bugging me anyway. I guess I should start by briefly reviewing the show for those who might not have watched it or have forgotten about it.
The show stars Angela Lansbury (the crazy-ass mom from The Manchurian Candidate) as Jessica Fletcher, a famous mystery novelist, who gets all ideas for her books from the insanely fucked-up situations she encounters whenever she visits friends, goes on vacations, walks to work, goes out to dinner, and takes out her trash. I'm assuming that's how she gets her ideas. The program doesn't go into her creative process so much.
So, here's the problem; Jessica Fletrcher seems all-together unfaised by the violence that surrounds her daily routine. I don't get it. I'm aware that it's just a television show and one that isn't even on the air, so it shouldn't be so bothersome, but it is. How is it that a woman can find herself constantly faced with death and seem fine? You would think that Ms. Fletcher, who is always surrounded by grief, anger and betrayal--all stemming from a death early in the program--would come to view herself as some kind of Grim Reaper. Whenever she visits her well-t0-do tennis pro friends; one of them dies. Whenever she sees an old friend who's now the sheriff of a small town, some dark secret comes out of his past because of her prodding. Is she unaffected by the pain that follows her?
There's no way any of us, on a daily basis, could deal with the mental weight of personally knowing at least ten people who have killed their rich spouses for the insurance money without requiring some kind of outlet. I've been thinking about this for days now and the only logical answer to me is that Jessica Fletcher takes all of these heinous situations and writes through the negative effects they have on her mind and spirit. And I'm not suggesting she's trying to profit from these acts, but rather that she is trying to deal with them the only way she knows how; she's gonna write a bitchin' novel about it. Whatever.
The other issue I have is with the antagonists on the show. I can understand the first season. Yeah, she's hunted down a lot of murderers, but maybe it was all a fluke, or she was really lucky. After the first twenty or so times though, you should really reconsider murdering your cheating wife when you know Jessica Fletcher is going to be staying with you. It's simple logic. Even if you're witnessing your new bride in bed with another man and there's a pair of scissors right next to you on the boudoire. Hey, think about it. Jessica fucking Fletcher is in the next room. Chill out until the old bat leaves and then cut the breaks in your wife's car or something. Simple. "No fuss, no muss" or whatever that phrase is.
I think those are the only two problems I have with the show. I mean, it also seems kind of weird that so many people take a long look at Jessica and then say "Well, I'll be a monkey's uncle. You're Jessica Fletcher, aren't you?" How many people know the faces of novelists in the first place and in the second place, how many people read mystery novels? I can't name even one mystery novelist off the top of my head. Not one. Yet ten people in every fucking small, broke-ass town in Georgia know Jessica Fletcher almost immediately.
