Took me a little bit over 3 months to get through the whole series. Very enjoyable. Season 6 was surprising all the stellar episodes it had. I especially enjoyed Emily Carlin, Emily Carlin... the series finale Happy Trails To You. Season 6 was a little heavy on the clunkers though. I gave season 6 a 6.2 rating out of 10.

A few terrific episodes: "Who Was that Masked Man?", "A Day in the Life", "Shallow Throat", "Freudian Ship", "Group on a Hot Tin Roof", and the finale, "Happy Trails to You." "Happy Trails" is better than a lot of much better-known sitcom finales.
