I just rewatched this fantastic 4 part mini series all together, after not having seen it since it launched back in 2008. It's so good. Neil Patrick Harris is excellent, as are all the leads, but he really does stand out. Dr Horrible was a 4 x 10 minute mini series made during the writer's strike that caused so many delays and problems for major productions. So Joss Whedon and his brothers and others decided to make their own little project rather than sit idle, and the wonderful Dr Horrible's SIng-Along Blog was created. Does anyone else remember watching it as it was released?
