In Search of... "A Call from Space" (1977)
The twelfth episode in the series takes a look at the various satellites in outer space and whether or not they're able to send off messages to other life. We also take a look at dolphins and whether or not they're trying to communicate with us.
This series certainly has a lot of fans and while I think some of the episodes have been good, there's no question that others haven't been nearly as impressive or entertaining. This here is one of the less interesting ones as the story itself is just told in such a bland way that you really don't learn too much. Yes, it asks the question on if we can communicate with other life but there's just not too many interesting stories or facts here to make the episode better.
