It’s quite clear (and has been for a number of episodes) that the series had a huge identity crisis and didn’t know what it was aiming for. Also here is the late, hulking Ted Cassidy who gives this material more actual quality acting than it deserves.
You’re going to be rolling your eyes at least a few times in disbelief. But this is, I guess, part of the charm with a series like “Man From Atlantis”. You never know what they’re gonna come up with next and it must have been a hoot for viewers to tune in when this aired initially.
