The straightforward way of setting up the series would have been to have Blake arrested in the course of Freedom Party activities, then mind-wiped, fitted up, and shipped to Cygnus Alpha. Instead, we have the whole (and rather anti-heroic) business of the SECOND arrest, at a time when Blake was pretty much minding his own business and conforming.
The Blake we see in all his other episodes is a strong person who dominates the situation, so TWB not only has a very different atmosphere from the rest of the series (it's more like the last episode of The Prisoner than the first of B7) but presents Blake as a hapless victim rather than the flawed hero I suspect he was supposed to be.
