The first season was great. Then, in season 2, the lead was fired and the show was deliberately dumbed down. It never recovered from there, though I'm told that season 4 was a slight improvement over seasons 2 and 3. I never saw it. I had stopped watching by then. I did see a lot of season 5 though and consider it the show's ultimate low point. The show was retooled once again, the second lead had been fired and the entire cast with one exception had already moved on by then.
