Why did they pick one of the only Diff'rent Strokes episodes that Dana Plato wasn't in? That couldn't have been a coincidence, especially since it wasn't a very memorable episode, there are so many better ones they could have chosen.
And yeah, I agree with most, Dowd and Lithgow were great since they were adults playing adults. This would have been so much better with young actors and actresses playing the kid parts. I'm surprised that any of the Facts of Life set was left after all of the adults playing teenagers chewed it up so bad.
