4. Dr. Horrible's Sing-Along Blog

The writers' strike, which began in November 2007, was the worst thing to happen to TV in 2008. But the best thing to come of it was this eccentric, tragicomic musical, which like the strike itself helped redefine what could be called "TV." Conceived as a strike-time diversion by Joss Whedon (Buffy the Vampire Slayer), it starred Neil Patrick Harris as the title character, a would-be supervillain applying for membership in the exclusive Evil League of Evil. Whedon released it online, where it became an iTunes smash and inspired a deluge of homemade Evil League of Evil application-videos by fans. Cramming hilarity, heartbreak and high notes into a half-hour, it reminded us that no labor dispute can keep a genius from using his powers for Evil, and for good.
