This is another ep along the lines of where the series developed with a greater concentration on more serious shows, and this was no different. I agree with the other review that the Collins song Mama was a perfect choice, although I'm a little prejudice in that this is the music I enjoyed as a teen.
The series definitely turned to darker ep's as it developed, and I don't know if that had anything to do with its going away. I watched sporadic ep's as most of the series run I was in high school and the navy so didn't have the time to watch them with they aired generally. Watching/Rewatching them as an older person I enjoy them.
