So, book adaptations of cancelled series.
I remember reading the Prisoner books - there were three. Well done.
I remember reading all seven Get Smart! books. They were funny.
I read a Welcome Back Kotter novel - one joke in it was really funny.
I read three Babylon 5 paperbacks - the Londo Mollari trilogy by Peter David. Excellent.
And I didn't read as many Doctor Who novels as some have, but I've read a few.
My favorite author wrote a Star Trek novelization. It sucked.
But the problem is, of course, that television shows are a different medium than novels, and novels can't do what TV shows can do, and vice versa. So why would I read one? Well, because the show is over, and I want to have more episodes, and I can't, but look, here is a novel. So there we are. The novelist has an almost impossible task. And almost all of them read like fanfic. The Prisoner ones had literary merit, but they weren't the Prisoner. The B5 paperbacks were actually really really good. And at times they felt like I was watching B5. But not really.
So here we are reading the Life on Mars novels. This is the first one. The author got the voices of the characters right. Except almost - too right. Gene's lines were perfect "Gene-isms" except that in the show, not EVERYTHING Gene says is a Gene-ism. He talks like an imdb list of "Great Gene Hunt Quotes!" Except for one line which is honest, straight, and sincere. It would have had a big impact, but it was lampshaded "It was such an uncharacteristic thing for Gene to say!!!"
This novel takes place after the last episode of Life on Mars. If you've seen the excellent series, you know how hard it was for the author to continue the story. The series had a pretty definite ending. One strength of the series was the interplay between Sam's life in the 1970s and his gleaning what's happening to his comatose body in the 2000s. How do we continue that tension after the series ended? Tom Graham actually found a way. So, there's that.
In TV-Land, there were two explanations for what happened to Sam, one presented at the end of Life on Mars, and one at the end of the sequel series, Ashes to Ashes. I think both are fine, but they ARE different. And in my mind, the "real" end to Sam's story is the end we saw on Life on Mars. Ashes to Ashes was, to me, a separate series, and its explanations don't carry over to the first series in my mind. In this novel, it is clear that Graham is using the Ashes to Ashes explanation, and that is a detriment in my mind; a small one.
Overall recommendation: If you loved Life on Mars, and miss it, then this book will ease the pain. It was an entertaining read, and enjoyable for what it is. If you don't miss Life on Mars, there are other books you'd enjoy more.
