In the extended cut of The Two Towers, some of Bombadial's lines and characteristics are given to Treebeard.

I found that Bombadil seemed slightly... stoned a lot of the time. In fact, in the brilliant lampoon Bored of the Rings, Bombadil's character is a drug-crazed hippy named Tim Benzedrine, so I'm not alone in that view.

I don't dislike the guy, though. He's a mysterious character, that's always a good thing. An embodiment of environmental ideals, too.
However, as Behold the Void has said, he didn't do one heck of a lot for the plot.

Incidentally, the true hero of The Lord of the Rings has always been, and will always be, Bill the Pony.
