Now do you see what I mean by an excellent way to start off considering the current situation?
While this ep was definetely important to the overall arc, you don't really need that much knowledge of the Scarrens, Peacekeepers, etc to really understand what was going on because it was fairly self-explanatory... not to mention it taking place in a familar environment... namely, Earth.
So new viewers can enjoy it and still get hooked by the "to be continued" at the end... if I didn't know better, I'd almost say they planned it this way!
