Yeah, I think a big difference with the Jailer is that the narrative so far isn't trying to pretend it's more clever than it is. Jailer was a walking, talking contrivance presented as a 420 IQ all according to plan schemer, whereas Incarnates are big bad dragons presented as big bad dragons. They drive the plot without hijacking it. The concept isn't exactly revolutionary or anything but I'll take safe and half-decently executed over trying too hard and making a gigantic mess of a villain.
