OK, I finally finished watching season one and here are my votes for best & worst.
The Best: Mystery in Wax
A woman famous for making Wax Sculptures of people also has an uncanny ability to predict the imminent deaths of people. After apparently successfully predicting the death of a man in the opening of the episode, she then turns her prescient powers to predicting Perry White's imminent death.
Even though I don't believe in people being able to predict the future, I'm kind of a sucker for stories like this. There's a definite feeling of dread after each of the woman's death predictions. Of course Perry doesn't believe in any of it, but everyone else around him is at least a little bit worried. When you throw in the whole Wax museum angle to the story and it makes for a pretty creepy (in a good way) episode.
The worst: The Evil Three
The basic plot of the episode isn't too bad. It's your basic Scooby Doo plot. A couple of guys try to scare Perry & Jimmy away from a country Inn to protect their claim to a hidden treasure. Nothing too special here, but not really God awful either.
The reason that I rate this episode so poorly though, is because it features one of the most unappealing characters that I have ever seen in ANY SHOW. I'm talking about the old hag. Not only is she rather unattractive physically speaking, but she also has a thoroughly repugnant cackling laugh and she's prone to belting out soul piercingly shrill screams at the slightest provocation. You really have to see the episode to appreciate just how unappealing she is.
