PLOT: Buck & Twiki are commissioned to explore a planet for signs of human colonization while the Searcher takes care of business elsewhere. The duo happens upon a widow and her kid son who are harassed by a Satyr, a goat-man. The situation takes a turn for the worse after Buck is bitten and starts to morph into a Satyr himself.
COMMENTARY: This is another very Trek-ish episode with Wilma and Hawk taking a backseat while the story focuses on Buck & Twiki on the alien planet. Speaking of Buck & Twiki, it's great having these two working together again, which had been absent from the 2nd season until now. This is also the second episode to feature the return of Twiki's original voice (by Mel Blanc). The quality planet locations are another highlight (not a lame studio set à la "The Crystals").
While Anne E. Curry (the widow) is beautiful, the producers basically make her out to be a plain Jane. Regardless, you can't help respecting her utter devotion to her long-gone husband. For those who require a hot space babe, Wilma appears in a skin-tight red spandex uniform at the close. The Satyrs and the demonic steed are actually pretty well done in a decidedly cartoony way for a series known for its cheesy (not so) special effects.
Although "The Satyr" is Trek-ish, it's unfortunately not as engaging as the typical Star Trek episode (TOS). The creators were on their way to working out the kinks in the 2nd season format when the series was prematurely canceled after four more episodes.
