If you love musicals, Neil Patrick Harris, evil plots, supervillains, love stories, or awesomeness in general you need to watch this immediately. It's on Netflix Instant right now. RIGHT. NOW.
It's only 45 minutes long, so it's not a huge time commitment. It was written/directed by Joss Whedon (Buffy, Angel, Dollhouse, etc.). If you remember the Buffy musical episode, it's like that, only 132234 times better!! I've heard rumors of a sequel. One can only hope.
