Rod Serling's "The Twilight Zone" is - hands down - one of the greatest TV-series in history. That said, I'm very much aware several episodes are mediocre, or even downright lackluster. This is usually because they are overly sentimental, too fantasy-like, or wannabe comical. "Cavender is Coming" is even worse. Far worse. This episode aims straightforwardly for laughs and slapstick, but it's an embarrassing and pitiable showcasing of inept writing, acting and directing. When I watch "The Twilight Zone", I want to be overwhelmed with Sci-Fi, morbidity and strangeness, but this installment only offers second-rate comedy. The plot revolves around a clumsy guardian angel who gets one final chance to earn his wings, but for this he has to descend to earth and guard over the even clumsier Agnes Grep. Dumb plot, poor acting, lame jokes, infantile sound-effects and whatnot. "Cavender is Coming" is one of the lowest rated episodes of the series, and it's also getting the lowest rating I've ever given to a "Twilight Zone" episode.
