[Gothbogg the Ripper]

I am glad they showed Radagast as the cowardly simpleton he was.
His apathy during the War of the Ring has always been absolutely indefensible to me so it was nice to see both Gandalf talking down to him like a child and Saruman ranting about the guy and his poor personal hygiene.

One of Tolkien's most intriguing characters and perhaps one I hate the most. A villain is expected to do evil things, a hero is expected to act with virtue, but someone so completely indifferent is just infuriating to me.
It suggests cowardice, something untrustworthy and rotten.
