It seems, looking at my scoring of episodes, I enjoyed the Pilot and The Children's Hour best. The first and the last ones aired. I think the Pilot was very good, even compared to Pilot standards. It gave quite a good intro to the characters. About the last one, I'm a fan of Tiffany Thiessen, and in this kind of show the guest stars play a major part in each episode. A guest star can make or break an otherwise coin toss of an episode, or elevate great stories to superb ones.
Behind my two favorites, also Heart of the Matter and Bachelorette Party deserves very honorable mentions.
