As a dissent to my contrarian ways of typically posting an opinon and option not listed in the poll, I do admit to voting for JRR here. I've read both, Narnia seried only twice (but "LW&W" more often), and LotR more than few (and [i]The Silmarillion[/i] a couple). Conan really isn't the most appropriate thing for me to put up there. It's not really a series so much as it's a collection of stories surrounding a central character that can be read in any order. I remember someone describing them as a tales you'd hear Conan telling in an inn over a mug of ale ("Then there was the time..."), you don't have to have read one to understand another, much less read them in any particular order. They're also of various lengths, next to the actual substance of them, I think that's the big draw for me. I can sit down and read a story that's a few pages ("The Frost-Giant's Daughter"), a few more ("Tower of the Elephant") a full length novel ([i]Hour of the Dragon[/i]), or a mid-length novella ([i]Red Nails[/i] or [i]People of the Black Circle[/i]). And they read fast. Even JRR's poetry & songs sometimes feel like a slog. I never feel that way reading Conan. But, back to my contrarian ways... I'd have to put Michael Moorcock's Eternal Champion (not just Elric) multiverse mega-series in the running for top series. While each individual series (Corum, Rlric and The Eternsl Champion) has a particular order, each series can be read independent of one another, in any order.
