This book isn't perfect, but I enjoyed reading it. Rob Grant's writing is as detailed and talented as ever, and this book is based on a few great episodes of a great television show. I suppose my major complaints about it are more personal than anything. While I admire how Rob Grant chooses to go beyond the details set by the original television show and change the story, I found myself loving some changes, but not appreciating others. For instance, we spend a lot more time in the Backwards universe than the show does. While it's an interesting location, I found myself frustrated. Without spoiling the plot, the specific changes for that part didn't appeal to my interests, and because I knew the characters would leave that universe eventually, I kept waiting for it to be over.
Another example is the excruciating detail of pain. This book is a lot more violent than the show was, and it's easy to see why. The television show, while never shying away from violence and dark humor, was still a goofy sitcom, and had to have everything wrap up nicely at the end of thirty minutes. This book, however, goes to a lot darker places, and puts these characters through even more hell than the show does. At one point, I even started to feel physically sick at something horrible that happens to Lister. (Well, I think it was something else. I blacked out for two minutes after a sudden stomachache and moaned/hyperventilated until I could take a nap. But I never found out what caused it and it happened right as I was reading that part of the book, so.... who knows?) While it was sometimes nice to have higher stakes, I would've liked the book to feel less like torture porn.
My last major criticism is about how the book uses one of my favorite characters, Ace Rimmer.... but I can't discuss it without spoilers. The most I can say is that while we get some fantastic chapters in his original universe, the way he leaves the crew is sudden and disappointing. He does get a lovely epilogue, though. Still, it made me sad to think about how much better his exit was in the show, at least from the point of view of an audience member who only wants the best for him.
I'll end this review with something I loved about the book- its cliffhangers. I know I'm only giving it three stars, but I couldn't put this thing down. Rob Grant ends practically every chapter with something that makes you ACHE to know what happens next.
Overall, if you like the show and don't mind seeing these characters in even more gruesome situations, give Backwards a try. Alternate universes may not turn out exactly like you want them to, but you'll definitely have an interesting time in them.
