I think the people who didn't like the episode missed several points, one do you need to become someone evil to stop evil, and to parents often reflect their own desires or missed opportunities, and dreams onto their children.I saw one review that said it was more fantasy than science fiction, not growing up in the age of Ritalin or any of the other drugs that are given to children these days, I think the episode brings up some valid points. I don't take any drugs, and never have, but the fact that there are so many advertised these days, and without truly knowing what the long term effects will be years from now, the true effects of these drugs remain to be seen.
