is right: What is on screen shows a fairly small village. And everyone else is right that Defiance is supposed
to be at least a small town. Babylon 5 had exactly the same problem whenever they tried to stage a riot or other mass scene. TV cheap just isn't convincing.
If your interest in the show is enough to overcome these monetary trials of willing suspension of disbelief, good on you. Personally, I haven't found the episode interesting enough to finish watching.
In some respects, the notion that young people would be influenced by alien dance and music was the series' most innovative moment.
