Unbeknownst to him, Hoss Cartwright has fallen in love at first sight with a woman of ill-repute (played in an extremely polite manner by Gena Rowlands) who is visiting her sister from racy San Francisco. This being 1963, the writers can't use the words 'jezebel' or 'prostitute', but the point is made clear when Adam Cartwright is seduced by man-hungry Gena right in her sister's front yard! The crux of the story however is a bit outdated, that a woman with a bad reputation is much like a leopard--she could never change her spots. Rowlands gets a good lecturing by Ben Cartwright--we even get to see the Cartwright brothers come to blows (minus Little Joe, who spends this entire episode hovering in the background). I'm not sure why the "Bonanza" stories couldn't feature each of the main characters equally when it came to tales of family conflict, but it seems the lead parts were divvied up week by week. This fifth season of the show was strong on episodes featuring Dan Blocker's Hoss prominently, and here he gets to utilize a colorful range: lovestruck rancher, clumsy gentleman caller, jealous boyfriend, hurt and angry brother. It's a triumph for both Blocker and Hoss, as we see a loyal and dedicated side to the big guy when it comes to matters of the heart (he even agrees to leaving his precious Ponderosa if his lady-love wants a life in the city). The film-stock used on "Bonanza" was terrific, as the colors just pop off the screen, and Rowlands (in an off-the-shoulder, Lily Langtree-styled party dress) has never looked so dreamy. Blocker, too, looks a might handsome, and his devotion to her is exceptionally heartfelt for a weekly western television program.
