Pratchett got Elves about right as to what they actually are. LoTR paints them as being some uberdemigod type immortals with smugmode on permanently. dm_of_the_rings gets the correct way to treat 'em:

OK, Aragorn's also an arse, but he knows a dodgy Elf when he sees one.

and yes, had to get it in early, because it might be a good plan. That I messed the html up so it's all visible? Yeah, that's me being crap.
