Tragically the original Captain Kangaroo Show is mostly lost to the ages. Of the literally thousands of original Captain Kangaroo Show episodes (something like 8000+ were made) less than twenty are still in existence. None of those are commercially available on DVD or streaming. There are a few VHS shows (like ten episodes) but those are all from the late 1970s to early 80s.
Anyway, this All New Captain Kangaroo is somewhat entertaining, but just is a pale imitation. It does have a few fun moments, but lacks the magic, and glory which was the original show. Thus, this all new show lasted only a short time.
