I've always wondered how "the trilogy" became the standard. Lord of the Rings and the Foundation series were, for whatever reason, put into trilogy format before it became "the thing to do" and were read by the largest amount of readers in that format. And considering that both works are the cornerstones of their respective genre's, it just seems like the ideal format for people.
Sort of like how because TNG got good in season three and lasted seven seasons, Trek fans started saying it takes a Trek show three seasons to get good and that seven seasons was the ideal number.
If LotR and Foundation had been quadrologies instead of trilogies, we'd all be thinking that was the ideal number since they've been the most influencial works of their respective genre's.
As far as reading....I find that I despise what I call "Elves and dwarves" style fantasy because it's far too derivative of Tolkien. And I only read LotR because it's THE classic that inspired and influenced fantasy for decades. Little interest in that kind of story and my interest in fantasy lay more with either the New Wave of fantasy writers like Moorcock or Zelazny or older writers like Vance, Ashton Smith, Dunsany, Hodgeson, Wellman, Lieber.
World building was incredibly fascinating to me for a long time, I built my own world, but not being a writer, I could do little more than create timelines, maps, etc. Over time that sort of thing stopped interesting me and I grew to appreciate more those guys who could create a world with a few words in a few stories.
I love these smaller worlds these days, rather than overblown and excessive world building...I'm looking at you Wheel Of Time, as they don't take forever to read, but feel "real" in the best tradition of imaginary worlds...if you know what I mean.
And it's a goddamn shame that Tolkien gets more recognition than Lord Dunsany (probably the most influential fantasy writer before Tolkien). Tolkien's big accomplishment was the detail of the fantasy world his characters inhabited.....but Dunsany had an almost supernatural command of the english language and was an infintely better story teller. Lyrical sentences that flow like water and amaze with their ability to conjure imagery simply astound me.
Sadly people today can't appreciate that older style of fantasy, often times feeling like it's too "fairy tale-ish". Gaimans "Stardust" was Gaiman doing his best Dunsany impersonation.
I'll leave with a couple of quotes about and from the man himself:
Inventor of a new mythology and weaver of surprising folklore, Lord Dunsany stands dedicated to a strange world of fantastic beauty . . . unexcelled in the sorcery of crystalline singing prose, and supreme in the creation of a gorgeous and languorous world of incandescently exotic vision. No amount of mere description can convey more than a fraction of Lord Dunsany's pervasive charm.
...H.P. Lovecraft...
All we who write put me in mind of sailors hastily making rafts upon doomed ships.
When we break up under the heavy years and go down into eternity with all that is ours, our thoughts like small lost rafts float on awhile upon Oblivion's sea. They will not carry much over those tides, our names and a phrase or two and little else.
...Lord Dunsany...
