They may be an asshole, but I'd take Stephen King over J.K. Rowling or Tolkien. The Towers series by him is incredible, and the ending is totally unpredictible, as is the rest of the story. It's about seven 900 page or so books, but it doesn't drag on and on about the fucking grass and the trees.
A part of me hopes it never ends. ~witwitch recent got a DD and ~The-Vibeke lost her shit. Again. I mean seriously, suck it up. She's a better writer and she's allowed to have her opinions (especially when she backs them up with very valid points).
I like fantasy too, but that criticism is valid. A lot of fantasy works like to crib off of Tolkien, and no matter how "awesome" a concept is it'll get boring if it's done a million times. You can be creative in pretty much any subject, not just fantasy.
It's not creative if it's the same tired concept every other story uses. Sure some people can put an original spin on it, but most of them... I don't see what's wrong with that person sharing their opinion.
Fantasy can be boring. I plan on writing a rather dark novel that's a strong turn away from the typical bunch. I like adding taboo topics into my work. The main pov is from someone who is deranged and "abandoned" by her parents; reunited with her brother as an assassin..No dragons, no elves orcs or other except critters I had made up. I think you need a little more detail and structure in your work (was reading your chapters), but don't make it too rigid.. I find fantasy like The Hobbit boring-I couldn't read that. I believe some find fantasy boring because of this grand "quest" that all fantasy books seem to have. Well-that's just not for me.
If anything fantasy writers are less creative. The meat of your stories come from beat to death concepts like dragons and magic that you didn't even come up with yourself. To write in a reality based capacity takes real creativity to make it interesting.
That isn't true for the jewels in fantasy, which are only hard to find, because everybody thinks they can write fantasy. Writing _good_ fantasy is just as hard as writing good reality based stories, and that is the problem, most less talented authors write fantasy. (alas, not me I'm a bad author who writes real-life based things)
