Pretty good story from Mike Tucker (who I think is a somewhat underrated writer). I like a lot of the ideas used in this one though it might have went on a bit too long. Briggs does some of his best Dalek voices while the rest of the voice cast are pretty good.
Viewed this through Josh Snares' animation, which I think is a bit too reliant on real-world models but still quite impressive for something made by what I assume is one or a few people.
