Any local newscast is easily the worst show on television, in my opinion. Journalists, particularly broadcast journalists, are usually the least educated people on any topic about which they must speak. You figure this out when they occasionally have to talk about something in which you are expert. They mucker it up so badly that you (rightfully) wonder "What else do they screw up?" The answer is: everything. You should believe nothing that a local newscaster tells you, because they say nothing believable.
But the second reason that local newscasts are so worthless is that they spend half their time telling me they "are on my side" or even "what you need to know". Puh-LEEZE. You turkeys say nothing that I need to know, and if I need to know it, I can read it on the internet at 10x the speed, and at least twice the detail, as you'll tell me.
Can you tell I really hate local news? My father-in-law just gobbles it up, and can't understand why I'm laughing in mocking derision most of the way through the "program". This strikes me as mostly a generational thing. He always got the news by watching it on TV. My generation reads it on the internet. I'll freely grant that your BS detector must be even more finely tuned for content on the internet than on TV, but this is only because TV news is mostly BS and it's easy to spot: whenever their lips are moving.
Beyond that, I hate American Idol, Biggest Loser, Survivor, What Not to Wear, and any other "reality" show that my wife laps up. At least she doesn't watch MTV anymore. "Sex for your kids, by your kids, on your kids" is not good programming, in my opinion.
I also think the History Channel and Discovery have gone down hill big time. Some of what they show may be entertaining, but history it's not.
