Leaving aside that debatable statement, there isn't necessarily a correlation between ratings and entertainment value. A lot of shows get bad ratings due to their timeslot or other factors. Farscape is one of the best sci-fi series ever made, but it constantly struggled in the ratings because of network shenanigans.
