More stories featuring aliens with bizarre medical problems? Sure, why not? The Sector General series remains a beloved locale and series of stories even nearly fifteen years since White's death dried up his seemingly inexhaustible supply of ways for the various beings and personalities on board the giant space hospital to interact with each other, to clash and come together to solve problems. Some of it is perhaps based on novelty (the number of decent medical SF novels can probably be counted on one three-fingered alien hand) or maybe the accessible format or interesting problems.
But the main reason is that it's hard not to respond to White's inherent decency and his belief that everyone should be treated decently. It comes through in nearly every story, as varied alien species come together, sometimes carrying extra alien species in their heads, to save the lives of patients from worlds they've never even encountered, sometimes for the sake of curious science but more often because it is a Thing That Needs To Be Done. There's a purity to that not often seen in the world of SF without getting too obvious or cloying, as too many times such sentiments devolved into Us Versus Them scenarios. In the world of Sector General there may be a Them but before too long they become part of the Us. That's refreshing and more in line with a vein of SF you don't see as commonly these days, when optimism was a big portion of the attitude of SF. In the years since as we've experienced various dystopias and post-apocalyptic scenarios it becomes hard to remember that a lot of writers believed with all sincerity that things would be better in the future. And they could convey that sentiment without getting all gooey, not turning a blind eye to the problems at hand of the day that would have to be solved, or the problems of the future that would need to be overcome. Sector General takes place in a world where bad things still exist but it can be solved with a little bit of ingenuity and a sense of teamwork.
Over the course of thirty or forty years, it's easy to build up that kind of comforting familiarity, creating this warm and fuzzy place in the minds of readers that they were eager to revisit again and again. But that familiarity can also be a hamstring and never more when you're trying to read many of these stories in a row. In the early stories White definitely felt he had hit open a formula and while none of the stories ever come across as crass or taking the audience for fools, a sense of repetition starts to set in. Read months or years apart, it's like the gentle easing in to visit an old friend. When you bundle three collections together in one six hundred page omnibus and then try to read them all over the course of a weak, White's flaws as a writer tend to come more to the fore.
To his credit, he does attempt to break out of his own formula but in the meantime exchanges it for a new formula. Stalwart Doctor Conway, the prime character in the early stories, gets assigned to an ambulance ship that takes he and his crew out of Sector General to respond to crashes and wrecks that are floating in space, to find if there are any survivors and then figure out some way to treat the survivors. The initial jolt of the change is bracing, but it's not too long before the familiarity begins to set in. Even the first two stories in the first collection have the same basic problem (the lone survivor of a wreck makes everyone mysteriously sick, even if the ultimate causes are different) and while the resolutions are inventive, they often come down to Conway once again going out on a limb and trying a solution that no one thinks will work (especially O'Mara, who barely seems to tolerate him sometimes).
What becomes grating at times is White's tendency to repeat known facts from earlier stories almost verbatim in his explanations, whether it's the description of the classification system, O'Mara telling us once again that he's there to shrink heads, not swell them, the various rules surrounding fragile friend-to-all empath Prilicla, how Diagnosticians work, Murchinson's inherent hotness, when we're told the same things in the same way in story after story, it starts to feel like the beginning of Mr Roger's Neighborhood, where the same routines were established and repeated to make us feel welcome. It winds up detracting from the stories themselves, and calls attention to how there's very little forward motion at times, sometimes frustratingly so. There are many times when you want White to delve further into just how Prilicla has everyone eating out of its empathic multi-jointed mouth or some demonstration that O'Mara really is a brilliant psychologist instead of someone who insults everyone all the time.
It's not until the last novel in the sequence, "Star Healer" that we get that forward motion, putting Conway on the path to reaching the highest level of the hospital staff (almost arbitrarily it seems, like O'Mara shows up and says "Hey, I don't really believe you're qualified but ready to go crazy with more aliens in your head?") along with some interesting problems that lurk just on the right side of not being contrived. White also gets better moments of lyrical beauty, like when Conway goes down to the cryogenic section of the hospital amongst the chlorine breathers. It doesn't entirely displace the problem of the novel being a series of problems that Conway has to solve until it's over (something the series rarely seems to shake) but by the time we reach the end we feel we've come to the natural end of him as a main character and are ready for him to be relegated to supporting status. Which in a way winds up being a gift . . . having given us the basic format and structure of the hospital, White can play with his canvas in more inventive ways. It's no real spoiler to reveal that the next two novels in the series are far more interesting, giving us more spine and bristle. Conway was nice, but he was there as a means to solve problems, not be a character. With him out of the way, character and problem can take equal billing, and the series becomes the better for it. But to get there you have to go through here first. Much like "Cheers", the hospital can't be the warm inviting place where everyone knows your four letter physiological classification until you've spent enough time there to become a regular.
