I can only rate the show as a whole and, considering it's been dragging me back ever since my first episode in 1988, they must be doing something right. Yes, it's never going to be all things to all people (nor should it be), but to me, it's a silly bit of escapism that never punches down. It's more 'Coronation Street' than 'Star Trek', in that it can switch from high drama to whimsy in a heartbeat, and that's a rare thing. Long may it run!
