The Invisible Enemy

Doctor WhoThe TARDIS encounters a huge, fibrous mass in space, and as it attempts to pass through the obstruction, a violent discharge from the central console knocks the Doctor out. He manages to set a course for a medical outpost, the Bi-Al Foundation. Barely able to explain the Doctor’s predicament, Leela leaves the Time Lord in the capable hands of Dr. Marius, a brilliant but eccentric pathologist (he has fashioned his portable computer in the shape of a dog and christened it K-9). But whatever affected the Doctor soon spreads to others at Bi-Al, and the Doctor is now clearly the center of a hive mind directing the actions of the infected. The fight to save the doctors and nurses at Bi-Al is a losing battle; the Doctor and Leela must take the fight to the source of the problem: inside the Doctor’s own body!

LogBook entry & review by Earl Green

Review: I don’t suppose I need to tell you what ripples this adventure sent through the history of Who-dom. Still, as legend would have it, the producers weren’t quite sold yet, and filmed two endings: one with K-9 remaining with Dr. Marius, and the one with K-9 boarding the TARDIS and almost taking over the series at various points in the future. I don’t mind the mecha-mutt in small doses, and actually he’s used quite effectively here. It’s when K-9’s appearance is all but heralded with deus ex machina neon signs later on that I grew to resent his presence.

A pale imitation of Fantastic Journey, this four-parter is one big delirious chase scene. If anything, the best parts to watch for are those creepy scenes in the TARDIS before it materializes on the Bi-Al asteroid. (Kudos to the BBC’s effects shop for the Bi-Al model work, by the way.) On the whole, Doctor Who utilizes the “lead character mentally possessed by alien baddies” plotline a lot less than, oh, say, any given Star Trek after the original series does. So when it happens here, it’s really a bit unnerving.

Overall, a nifty little check-your-brain-at-the-door romp that is both surprisingly lightweight and dark and menacing. Now, if only they could explain why the Doctor has Greek architecture floating around in his head…
