The premise is interesting but I don't think it was executed properly. In fact, I found this episode not very touching and downright silly at times. Watch the scene with Charles explaining the plan to Caroline and her overreacting. It was an early episode and I think that Karen Grassle was still fleshing out Caroline's character and how she would respond to things. As for the 'moral of the story,' what exactly was it?
The children were busted by Mom; they didn't come to any realizations on their own. She had to confront them first. And what kind of Mommy Dearest must she have been that all three of her kids didn't come around? There is no explanation for why there was the lack of visits, and maybe they came for the funeral to collect the moola, LOL. Why should I be touched about THAT?!
