Interestingly, one of the first "Science fiction" works was actually Mary Shelley's Frankenstein, which was first published in 1818, and inspired by various experiments and science of the epoch. I don't have much time, to reply right now, but I have to agree with Petratch's Love, in that because a book is widely considered to be a bestseller and "popular" does not necessarily indicate that it must be somehow inferior and unworthy of one's attention. I think one can realise that cliches exist in every area, and genre stereotypes don't always reflect the quality of the particular work. There are always going to be fantastically original and innovative books spread across each genre. One of the the most thought-provoking books I read early last year was actually a highly realistic Science fiction novel, which was written by a visionary futurist and presented an account, which is result of much in depth research and serious discussions with those professionally involved in certain scientific fields, which feature heavily in the whole work and are woven effectively by the characters and fascinating theme. I learned it has (along with another by the same, though still not popularly recognised, author) been adapted for other mediums, though not widely studied as it is quite a recent publication. I have also read books by Jules Verne and H.G Wells, but must admit to reading more non-fiction, but do agree that the typical Sci-Fi book differs in style from the usual book in another genre. Many who have written highly successful and exceptionally prolific Sci-Fi works have also had some form of scientific training and studied in a choosen field before they even wrote their masterpieces. Someone like H.G Wells, and Isaac Asimov are often noted for their more strikingly simple style, though this specific approach is able to convey their ideas very well. And there are different degrees of "fantasy" where some may be envisioning the most unrealistic goals and situations. If you spilt it into sub-catagories though, I think "mythical wizards and sorcery schools " is much different to a more realist work presenting a possible account of the future, where science has heavily advanced, and technological development is significant to societal changes and improvements. I think the former is more on a par with the seriousness and likelihood of unicorns and elves suddenly floated into the atmosphere, and obviously not likely to ever occur in the future. Though this to remains a profoundly diverse genre, and the quality and scope varies.
