The popular sing along blog Dr. Horrible was picked up by Hulu.com yesterday and is once again free to watch. The show had a free premiere week on Hulu and then switched over to being available on itunes for a couple dollars. I'm guessing demand was high enough that Hulu ended up paying Joss Whedon and company some money for the show. This hopefully foreshadows that sales of the DVD will also be strong. I was remiss in posting about Dr. Horrible when it came out since it seemed to have magically spread across the entire blogsphere. I'm guess the nerd appeal of The Guild's Felcia Day had a lot to do with it being covered by most of the major MMO blogs.
Anyways if somehow you haven't seen it yet I suggest checking it out. It's something new that you probably haven't seen before and it actually quite funny. The songs are catchy and also fit into the story without being contrived. You don't even need to be a fan of musicals to appreciate it. Just read some of the comments on Hulu and you'll see a lot of them say things along the lines of "I normally hate musicals, but this was the most awesome thing I've ever seen". The last act of the show has mixed reviews mostly because of the ending. Still the impressive support for the show probably hints that projects like these will start to become much more common in the future.
Update: Joss is considering a sequel according to some news sources.
