I was very young when this was first aired but I remember watching it. As a child, I recall every episode had very tense situations, but it was captivating. Mark was not much older than I was, so I was able to relate to him and his situations. As an adult, I have a different perspective, but it has not lost anything with the passage of time. Stories are interesting and many carry moral and ethical lessons. I think it is worth watching for anyone of any age or generation. The fact that it does not have all the polish of today's shows does not detract from it.
