Most people find their first science fiction book in a disorganized accident. Picture yourself as a puberty-aged kid forced to go to some family gathering where the house smells of old people and there is absolutely nothing to do, for hours. Eventually you take refuge in the bathroom and there stacked on top of the toilet tank are a pile of dog-eared paperback books with swollen pages from too much moisture and covers that look like really bad quality comic books. So you sit down to do your business and thumb the old things open. One clings to your sticky fingers.
That's how they hook you, the writers of pulp fiction, when you are trapped in the void of your own mind. The price of admission is a big red ring on your ass and a plundered book stuffed into your underwear as you clandestinely seek out some isolated privacy to - read more. Every science fiction fan knows that the objective is to read everything, just not on the toilet. There's just too many for that level of privacy. Be selective. Go for the good ones first and avoid the swirlies.
So what counts as the best science fiction series? This is a tricky question to address indeed. Book favorites are like 'holes -- everyone's got one. I've tried to sort out the gold from the silt in the genre, drawing from a range of older classics and newer works from various science fiction subgenres.
For the rankings here, I look at the series as a whole, the level of impact the series has had on the genre, the quality mantained by the series as the books progress, the quality of ideas presented in the book, the quality of the characterization (something that earlier classic science fiction works had which newer works put a lot more emphasis on) and of course, how damn entertaining the plot itself is.
