I find it a bit unnerving how they come right out re. the behavior modification issue and acknowledge that they are, indeed, attempting to do just that. And to intimate that a parent could reasonably expect to get "the real kid" back, once Elan has done their magic.
And, of course, the tried and true, thinly disguised scare tactic, "some of these kids might have ended up dead if they didn't come to Elan," to rein in the still-doubting parent contemplating such a choice for their child...
These people purposely lounging around in chairs outside, seemingly so laid back; I'm sure that was a calculated move on the part of filmmaker. Such a contrast with the tortuous soul searching the kids must go through.
