Their lack of knowledge on what food tastes like, yet they seem to know how to use a computer once they get the password right. They seem to know how to drive cars, run real fast, use guns and yet they can't figure out what's fake on social media, heal a body who is addicted to drugs, but they can heal a mentally challenged body?
Well, she's not healed. Not completely. And I have to admit there's so doubt in her character but I let it slightly because of the romance. That drama between the carer and the patient is well written and it often to goes to very extreme to shock the audience. And addict stays addict. There is no cure. You need to be really though to ween opioids out. It's just it's thousand times easier to replace hard stuff on chronic pain patients with CBD and that way bring them down instead of making them methodone whores.
On people who aren't in the pain category, the challenge is much tougher, because you have to strengthen mind at the same time as build up tolerance. And most of the people don't give up with snap of fingers. They try and they fall. Just like you see in this series. These people need a mentally though Traveller to cure the addiction. A super smart person is hardly one and the history is filled with examples of these geniuses actually accelerating the process and end up six feet under at the end.
Sad but true. Maybe the way they did it in this series didn't please most of the audience, while I did find most MC's quite intriguing.
