Re: David S. Goyer IS the Script Writer! - Part 2
Joss Whedon has not produced many movie hits because his background is in television. Most of his career has been on TV, where he has a distinguished career from Buffy and Angel, Buffy often being ranked as one of the best shows ever made.
He's a good writer-director, and between Buffy, Angel, and Avengers, he's had a decent career. He also contributed to the first Toy Story script (I'm not sure who did what), and a few other works.
