I know it was hard coming up with two fantasies an episode, especially back in the late 70s and early 80s where a series got a contract for more episodes than they do now. So maybe I'd cut the writers some slack if they same writers had to come up with all the stories, but they don't. And this late in the series, possibly all the good idea had already been done ... and done ... and done.
Early in the series there were some very dramatic episodes, By season five they seem to be going for laughs, and more often than not striking out.
Jimmy Dean plays a comic who was an orphan, and his standup routine makes jokes using an imaginary family. His fantasy is to meet the family. Predictably, things don't go all that well. Why they'd turn him into a comic instead of his native talent, singing ... who knows?
The second fantasy are two young women who want a husband, and Tatoo as teamed up with a computer programmer to find the prefect husbands. One problem with this episode is Tatoo's speech. You can understand most of what Herve is saying. Ricardo Montalban even remarks on it in a take that made it into the episode! The second problem is that the "technical language" used for the computer and the programming, predictably, is ridiculously ignorant. And then both are slated to marry Roarke. Again, supposed to be funny but just painfully lame.
