Judge Judy Makes Me Feel Better than Everyone Else
But I think what I find most satisfying about the show is that calls people on their b.s. And it never feels wrong, because the ones she lambastes appear to be liars or thieves---you don't often see her coming down hard on a person who is organized and straight-forward, but she sure as hell torches those who can't get their stories straight. So, you get to watch the bad guys get fined for hiding the money or the angry girl made to pay the $3,000 for smashing in a stranger's windshield and you don't have to feel torn or ambiguous about it.
This is what happens when you live in New Jersey. You spend so much time in your car, getting angry at people for bad driving, that a show about poorly educated people with bad tattoos who make poor life choices becomes a source of welcome release.
In case you want to read what the NY Times thinks about her, here's a link to an article about the show and her durability (and likability off screen).
