What it is:
Conceived as an “online miniseries event” during the 2008 writers’ strike, Dr. Horrible’s Sing-Along Blog is a 42-minute musical romp that bears the distinctive stamp of Joss Whedon.  Neil Patrick Harris (How I Met Your Mother) plays the title character, who video-blogs about his twin goals to join the Evil League of Evil and to woo the fair Penny (Felicia Day, of Whedon’s Buffy the Vampire Slayer and the Web series The Guild), a woman he met at the local laundromat. Dr. Horrible is foiled on both fronts, however, by his arch-nemesis, the self-absorbed superhero Captain Hammer (Nathan Fillion, Whedon’s Firefly).

Why it’s Significant: If you are already a Whedon fan, you’ve likely been enjoying Dr. Horrible since it initially hit the internet. Don’t overlook the slew of special features that are only available on the DVD, though. For those of you who are Whedon newbies, if you like super-quirky humor, musicals, and science fiction–you’ll find yourself watching this repeatedly.

Note: This DVD can only be purchased at Amazon.com.
