At this point the goal posts are in the delta quadrant...
No two shows are exactly comparable but for the purposes of the point I was making (that I felt they could have screened the first episode at the convention) they are perfectly reasonable comparisons. All I was trying to say was that it is fairly common for genre shows to do those kinds of early screenings, that it seems to be a popular marketing tactic.
Besides, the real reason for my post was to ask when we think it will screen for critics and I haven't seen one response.
