I think what kind of bothered me throughout the planning phase of getting 52+ kids out was "how the fuck are they gonna fit everyone in the plane".
We saw in a previous season that getting a plane in and out of Gilead was difficult, even for a small crop duster, and yet here we are with a literal airbus landing in an airfield with zero resistance (and a singular guard), and able to take off without any sort of countermeasures?
A "Staff meeting" can only go so far to divert attention away from it, but having an open airfield big enough to support a full-sized jet (regional or otherwise) with zero staff onhand to notify people of a plane landing is a bit of a stretch of suspension of disbelief, considering the rules the show itself established in previous seasons.
Likewise, if they're going door-to-door to find a single lost child, and presumably the other 50 or so children are also missing, how did no one think to
a) go check on their own kid
b) if they were all drugged or passed out too, how did the people conducting the search not break down a door when no one answered?
Finally, the roaming search party scene in the woods with the searchlight.. I was eyerolling at how blatantly they were missing the swarm of people moving by. Even in dark conditions, that light would have some falloff, and with all the girls WEARING PINK, your eye would catch some movements (and you know, point the light down a foot or two!).
The finale was fine, but there were so many plot contrivances / matters of convenience during the escape where I checked out.
