This film showed up on my Netflix recommendations. It said it came up based on my interest in The Princess Bride and Serenity, and it had a high rating. So it got my attention. After reading the synopsis ("...supervillain wannabe Dr. Horrible boasts about his exploits via his Internet video blog and dreams of defeating his nemesis..." "...musical comedy..."), it sounded too good to pass up. What I didn't notice was that the film was written and directed by Joss Whedon (Buffy the Vampire Slayer, Firefly), and that it stars Neil Patrick Harris (Doogie Howser) and Nathan Fillion (Captian "Mal" Reynolds from Firefly).
So, this sat in the queue for a while. We would sit down to watch something; Dr. Horrible would be suggested, then declined, as we didn't quite feel up to something that outlandish.
But tonight, we watched Dr. Horrible. I liked it instantly. I was continually amazed at the outstanding quality — especially the music. I never knew that Neil Patrick Harris and Nathan Fillion could sing — they both have really great voices, as does Felicia Day. (My husband later recalled that we actually saw Harris in Rent. He was really good in that, too. But I enjoyed him on film more, because on stage you don't get to see people's faces very clearly.)
The film was funny and clever, the song lyrics were brilliant, the story was well-written. The acting, singing, and production values were all great. I loved it. I think you'll either love this film, or else it will make your brain self-destruct. In my opinion, worth the risk.
