Highlander

After breaking up with her Immortal boyfriend, a woman starts a series of tawdry romance novels retelling his story. Events are twisted and distorted to goad him by making him an ugly, lampooned chariticure villain. Episode starts off as a parody of romance novels, becomes a parody of highlander, then becomes a parody of itself. When you insult the source material, you cease to be 'creative' and become a prick That's what this episode does to the series and the original movie. It stops being funny, but doesn't realize when it goes too far. And the music cues for the catfight scenes between the author and Amanda are annoying as hell. It was actually mostly fine and innocuous, until the author breaks down in front of Amanda and starts crying like a bad flashback to "My Best Friend's Wedding", at which point the joke becomes an insult. Instead of slapping her in the face and telling her to get her act together, Amanda takes pity on her like an ugly poodle and works to get her back together with her man.

The writers of this episode have only 6 other credits to their names: so far all of them episodes of Highlander I've hated.
