It was raining in the city by the bay. A hard rain. Hard enough to wash the entire cast of \u201cMagnum, p.i.\u201d over from Hawaii for an episode that\u2019s entirely film noir pastiche. It\u2019s not bad, though it misses some casting opportunities, exposes the lack of women regulars in the show, and is inexplicably shown in color when it should be shown as it originally aired\u2014in glorious black-and-white. Turn down the color setting on your 4K HDR and enjoy Magnum, by night\u2026 until Higgins wakes you up, anyway.
