I don't think it's necessarily his affinity to nature that is his failing (at least in respects to the books)...with the movies who knows what Jackson was thinking. He saw an opportunity at a bit of artistic license with the character, and he decided to go with a standard archetype of the socially awkward, probably strung out on hallucinogenic mushrooms, hermit. I do have to admit here, I don't expect well written characters from Jackson's movies, he writes characters into archetypes and I've come to expect nothing more from his characters.

But, it's not so much Radagast's affinity to nature that is his weakness. In Saruman's mind, I think that's how he looks down on Radagast, but he also looks down on Gandalf's "childish toys" and interest in hobbits. Saruman is a high-brow prude who rarely hides his arrogance. Gandalf, however, does note Radagast's worthiness as a wizard with his knowledge of herb lore and animals.

Radagast's weakness comes down purely to his apathy and complacency in his mission to strengthen resistance against Sauron. I believe as Galin quoted earlier in the thread, Radagast didn't have much courage, and this can be seen when he tells Gandalf about the Nazgul and Gandalf notes that he races off as if the Nazgul were on his tail. Also, he was more of a friend and confidant to birds and animals, not exactly a "Steward" in charge of care-taking. I use Steward here in the same way Gandalf does when he tells Denethor in ROTK he too is a "Steward." A steward in the sense of a care-taker, or shephard. It's said that Gandalf had more respect amongst animals than Radagast:

'it is clear that Gandalf (with greater insight and compassion) had in fact more knowledge of birds and beasts than Radagast, and was regarded by them with more respect and affection'

This is from Hammand and Scull's LOTR Companion, in Tolkien Papers - "Radagast the Fool."

When we think about Gandalf he's a character always in motion. There is never a place that he seems to stay at for long, not become static in a dwelling (Saruman in Isengard, Radagast in Rhosgobel). And he's always travelling over Middle-earth to strengthen and tirelessly make sure there is resistance against Sauron. His approach is one mostly on the the peoples of Middle-earth, but he obviously had the respect from Gwaihir and the eagles. And Treebeard feels he's the only wizard who really cares about "growing things."

Radagast on the other hand, is just too complacent and static. He would have a different approach than Gandalf, being associated with Yavanna and his love for nature and animals. I would bet if Radagast, had been a tireless "wanderer" like Gandalf, and did his best to strengthen the resistance in Middle-earth's beasts and in the earth itself (I mean, there is strength within the earth itself, as evidenced with Saruman overlooks the Ents), then he probably too would have succeeded in the Istari mission. For Sauron also had many birds and beasts in his service, and had Radagast done more to counter Sauron's own influence in the animal/nature realm, but he does not...and that is how Radagast fails.
