16. He Creates Great Characters
If I look back at my favourite characters in the last 15 years, a large portion of the memory is taken up by Whedon creations. Theres Buffy of course, Angel, Mal Reynolds, the main guys; but then when you look deeper, even the supporting casts are great. How can you forget Giles, Wesley Wyndham Pryce, Xander, Spike, Willow, Wash, Jayne Cobb, the list goes on. When you look at it, its little wonder Whedon was able to do so much with such a large ensemble of important characters in The Avengers; hes had years of practice getting that balance just right.
