James A. Stewart, DVD Verdict --Dr. Willoughby opens on the set of Dr. Willoughby, quickly establishing that, while Dr. Willoughby is a crack surgeon, you'd probably rather do your own bypass than let Donna Sinclair anywhere near you, even if she's not bearing a scalpel. She drops an f-bomb at co-star Ralph, angry at his ad-lib. As the show goes on, Donna turns out to barely know her son and brother, constantly sabotages naive younger actress Crystal with some really bad advice (and even suggests to the writers a storyline in which Crystal's character gets acid in the face), and has to look up Finland when she learns her soap is now on the air there.
To play an actress playing a surgeon, Joanna Lumley apparently had to study making funny faces. Fortunately, she did her job well and you might even laugh as soon as you see her previously cold visage start to twist. "Scandal" makes her gradually shabbier appearance as she becomes more haggard the main gag, and perhaps the series' funniest.
The secondary plots are usually left to Brian Protheroe as Ralph, a neurotic actor who tends to blow up a lot; he's usually dreaming of filling a gap left by a departing Donna, at least when he's not fearing his own abrupt departure. The strongest supporting character is Emma, a producer who begs to get out of her contract--and away from the difficult cast.
Dr. Willoughby generally has a realistic look to it; it appears to be filmed on an actual soundstage and backlot. The backdrop actually makes the silly, (hopefully) exaggerated gags on the show seem a tad more realistic, which adds to the humor. It's interesting to note that several of the actors, including Lumley (a veteran of General Hospital and Coronation Street), have experience with TV suds.
