I am a huge fan of fictional writing and movies and whatnot. It helps you reach a higher realm where the ordinary stupid people are generally absent. Science fiction is a one kind of fiction where imagination of the writer does escape to outer space.
Us science fiction writers take science and technology to a higher altitude altogether. But getting to this altitude is a task in itself and one may wonder if these heights could be scaled...No famous person has said this, but the one who has, is indeed great (sadly, it is not me, either). But this statement is true. These sci-fi people make some weird machinery or technology or idea up and make a story about it. This can serve to be motivation for budding scientists and inventors, but it can also end up like a string theory paradox. You know it can be there, but you can't prove it to be. People have died trying to make stuff read in books.
Science fiction shows like Doctor Who, Star Trek, etc. are shows, where the concept of SCIENCE fiction is overshadowed by the plot and story (offense intended Whovians, Trekkers, alike). When you make a Science fiction show, you must have your science stuff predefined, in my opinion. I learnt about the anatomy and biology of the Doctor(s) much after their troubled past and sociopathic tendencies. Even I find this a little wrong when I say this, for it is finally a show meant for entertainment and enjoyment and not necessarily education. When sci-fi shows are made, the science and complexity behind the ideas and bodies of characters is considered as trivia.
The entertainment factor is a must, you can't deny that. There can't be people as technical and critical like me everywhere. There will be people with a less critical point of view for "Science Fiction" shows. The producers in the end, have to make profits by their show. That is criterion number one. But, let me tell you, as pure entertainment and fun, these shows are not at all bad... I just find them not upto the mark of SCIENCE fiction shows.
The BBC show, Sherlock, cannot be considered as a fictional series. But the reason why I like that so much is that the science behind his investigations is so concrete and wonderful it leaves me amazed! It is crime investigation show, true, and most crime investigation shows do have concrete science backing their plot, but now the entertainment factor comes into play. The actors and the dialogues and the plot is immaculate and perfectly cogent. I can keep on ranting about the greatness of "Sherlock", but know this, it indeed is great and to match the intellectual level of Sherlock Holmes would indeed be an achievement!
Now onto out-of-this-world fictions! The finest book I have read so far on this genre is JRR Tolkien's 'The Hobbit'. It is a book which was almost never boring. Now that is an achievement. I tip my hat to you, Tolkien. Tolkien's Hobbit has a great story. It is a pure literary work, by the way. He has incorporated all those weird species of people we have been hearing of since kindergarten. Dwarves, elves, goblins, orcs, Wizards(notice the capital 'W'). All these species of bipedals thrive in a place known as Middle Earth. They have their conflicts, their rivalries, old scores, resentments, etc. What I believe is Tolkien has managed to encompass our modern day society with its internal rife and speculation into this place called Middle Earth and has depicted everything precisely.
Lord of the Rings is a classy fiction novel which I have come to love to bits, for it is a pure literary and fictional novel. Tolkien has a healthy imagination and great command over his words which always manages to captivate me.
Another thing I really liked about LOTR is that Tolkien published this book called the "History of Middle Earth". Now because of this book, you get to know the backstories of all the clans and tribes of Middle Earth. Now that is what I would like from writers all across. Whenever you make up a character with demons within, problems or fears, always try to give a brief description of how they actually originated. Tolkien just doled out a huge book for it all, but one need not go to such a great extent for this.
So what I basically want to say is, give a reason for everything you write. Don't just add stuff to your story just because you wanted to. Characters who don't have much importance, and are quickly cast aside are remembered by people. Dobey from Harry Potter, well, he made an appearance in 'Chamber of Secrets' book and directly at the end in the 'Deathly Hallows' book. But what I especially liked about that was, Rowling gave him an honourable hero's death. People actually went out of their way on making posts honouring Dobey and all that on Tumblr, Facebook, etc. The Head Counsellor of Hephaestus Cabin, Charles Beckendorf from the Percy Jackson books was also given a hero's death. Same applies for Silena Beauregard, Michael Yew, etc. What I am trying to say is, don't just ignore the rather unimportant characters in your story. People tend to remember those particular characters, so honour your readers by remembering them yourself, budding writers!
And if you have an idea for a story, don't hesitate to try. You might crash and burn completely, disproportionately wrecked. Then, you now at least know how to not write a good story and work upon that. If your language is good, grammar upto the mark with a slightly strange story which people IN GENERAL don't like, don't really worry. There will be those stranger, unusual people like you who will like those stories and try to magnify your fanbase. You just have to be consistent. And always avoid stupid mistakes, please, that is a must. It all works in the end, you just have to work on it. You must be a spider, weaving new stuff as you go along; and you must, you fucking must know how each and every thread in your web dances! If you do, then great! You are good to go! I will be looking out for your next book!
If it is good, I will recommend! If it is bad, I will demolish it completely with a scathing review! All the best!
