Think what you like but pretty much all writers including the ones I mentioned all say the same thing. The first thing any aspiring writer needs to do is become widely read. So that you become influenced by all that has gone before.
Um, I don't mean to be patronising, but do you know what plaigarism actually means?
Come on people you have read the same forewords and interviews as I have they ALL say "I was inspired by" this set of books or "I was reading" such and such author or "I thought why dont I do a modern version of that story".
And? Surely that's what fiction is - a creative response to the influences that have shaped your life, the people you've met, the places you've been to, the books you've read. I don't even see how someone would
begin to write a book without any reference to or inspiration from any outside stimuli whatsoever, unless they'd lived all their life trapped in a metal box, fed through a tube. And then it wouldn't really be a book worth reading.
Even bloody Tolkien said where he got his ideas from.
Are you having a laugh now? How can you genuinely equate Tolkein's being inspired by old European myth cycles to craft one of the most important and original fantasy trilogies of all time to Mark Millar's contemptuous scene-for-scene ripping off of blockbuster films?
You can't seriously think that 'having an idea' equals plaigarism?!
