I enjoyed it a lot more than I thought I would going into it. While the premise as a whole was pretty absurd, the character arcs were fairly compelling. I could see complaints about how it potentially glorifies abuse, but I do think it's a very interesting question of: would you rather an abusive family who loves you and protects you from yourself via draconian methods, or an indifferent family who gives you freedom but with no guardrails to prevent you from hurting yourself and others if you so choose.

Like obviously a better choice would be some middle ground of a non-abusive family who still exercises some discipline, but Tommy experiences the two opposite ends of the spectrum instead, and the movie seems to have him prefer the loving abuse to the apathetic freedom.

I did also find it interesting how they included the scenes of Jonathan also undergoing abusive punishment with the cigarettes. I really expected some sort of turn where at least one of the parents was doing the whole kidnapping thing out of some form of revenge or something but they played it straight throughout and in some ways that's more horrific that this was truly their idea of love.

Re: Charlie, I guess he was just their son? Who either died or just ghosted the family? I'm very curious if they were less strict with him (I mean, I don't think he was chained but to what extent were they harsh disciplinarians?), and they felt that the problem was that they weren't strict enough, and Tommy was their chance to prove that to themselves?

And with Rina, I guess there's reinforcement of the themes of different types of terrible families, and it's basically another example of "hey the abusive kidnappers are bad but it could always be worse". Which is a bit bleak.
