Elenquesse - oh, surely not Pippin! He saved Faramir, after all, and think of how things would have been if he'd been killed. And by looking into the Palantir - heck, even dropping the stone in the well - he brought about events which eventually turned out well. Things might have gone very badly if Gandalf had looked in the Palantir, and if he hadn't died at Moria and been reborn...well. Not that Pippin did those things *intentionally* but still, he was a handy tool of fate.

Have to agree with everyone who mentioned Mim - nasty little guy.

As for good characters that we dislike (I can't count Mim as good) I'll have to say Tom Bombadil, though a lot of that is due to having read "Bored of the Rings" and being unable to shake the image of Tim Benzedrine. Unworthy, I know. So my other candidate will be Ghan-buri-Ghan. I don't know why, but the Wild Men just left me cold, and he was irritating to read.
