Perhaps you're familiar with the man. He's done some stuff you may have heard of - Buffy the Vampire Slayer, Angel, Firefly, "Serenity," Dr. Horrible's Sing-a-long Blog, the comic book series "Fray," "Cabin in the Woods" and some little movie called "The Avengers" which came and went at the theaters.
Whedon's work has a lot of heart in it. The characters feel real and they resonate with you long after the shows have left the airwaves (I've watched the series Firefly about a million times now, and it never gets old). He also has a sense of humor that is much loved by this
So, Happy birthday, Joss Whedon. I hope you get some shiny presents.
