As a previous poster said, the reason why they all appear to be so incredibly stupid is, 1) because they have guidelines that they MUST follow, such as having to contact and meet with members of family, and not being allowed to stay in one location for longer than a single night, and 2) it’s obvious that the whole thing is scripted as fuck in these later series.
I believe the only genuine series we’ve seen of Hunted is the original series one. Then, all the stupid rules were brought in to make it so much harder for the fugitives. Having to all start in one place, having to receive messages about the collect point which then makes their location live to the hunters, and so on.
I would be very, very surprised if most of the later series aren’t scripted. All this nonsense with Toff and BoJo’s dad at the train station, “Oh dear, I just don’t know where he is, oh look how big this station is.” I mean, at least TRY to sound convincing.
