I thought the show was great. Coupled with Fantasy Island of similar genre, it used to provide two hours of "winding down" time every Saturday evening.
The lead parts were usually well cast and well played, though they were rarely lead parts in any particular story line: they tended to be segue roles as the episode drifted from story to story over the hour.
One common complaint I hear is that the show relied on has-been actors past their prime as guest stars. As I watched the show, I found this neither accurate nor relevant. So what if they did!! Let the hot actors of the day field the hard roles. Let those approaching retirement allow me to end the week, entertained with levity.
