Dr. Horrible's Sing-Along Blog (Blu-ray)

In his internet-distributed miniseries DR. HORRIBLE'S SING-ALONG BLOG, Joss Whedon puts his chorus where his comic books are, uniting once and for all his loves of sci-fi and musical theater. Broadway vet Neil Patrick Harris stars as the title's cut rate supervillain, a wannabe who's always one step behind his preening nemesis, Captain Hammer (Nathan Fillion). The hero thwarts Dr. Horrible's schemes and courts his dulcet-voiced, do-gooder crush, Penny (Felicia Day), a sad fate the evil doctor laments via blogs and hilarious, brokenhearted ballads.

Written by Whedon with his brother, Jed, the show's universally catchy track list strikes the director's trademark balance of snark and earnestness, most notably in Harris's yearning opener "My Freeze Ray" and Fillion's third act show-stopper, "Everyone's a Hero," a spot-on parody of vaunted superhero icons.
