After trying the rewatch, and failing after six episodes of NX (shame I remember loving it back in the day and I wanted to see the episodes Marsters was in), I decided to look it up. I couldn't remember when Grant Goodeve's character left or how. (Satellite Dish fell on him and sometime in the second or third season?).

Yeah, there was a lot of hostility on set. And various actors didn't get along. The actor playing Joel Fleischman wanted out, and asked for a raise early on, and was repeatedly denied. He went on to play in Numbers, and various films. It was not a happy set, from what I've read, although no where near as bad as Ally McBeal or Sleepy Hollow or Moonlighting.
