Any Dollhouse fan should know by now that last episode of the first season, called Epitaph One, didn't air as part of the programming schedule, causing almost a riot among the fans. Instead it was promised to be released on DVD, and here we are. The complete season will be available on DVD and Blu-ray very soon, and short scene from the episode was released to show what's the whole thing is about. I am not sure about the details, but it looks to me like a prequel to the series.
For people that still don't know, rumors reported that the second season was approved by the network after execs watched this episode, that was done with lower budget and with different approach than all other episodes. Apparently they liked it, and thus second season will be unleashed upon us, probably next year.
