A scene in the film when the grandad shot an arrow at Ben, we are supposed to believe he's the one in the wrong here. This is changed when he talks about how Ben is raising his children the wrong way like how one of the kids slipped and broke his wrist. When we watched that happen it didn't feel that wrong as it's in their nature and style of living but when the grandad talks about it being child abuse we reason with him and are on his side. We change our attitudes towards Ben throughout the movie as he trains his children at the start like killing animals and climbing cliffs but through others we find what he is doing was wrong although he's not the villain in this film. We reason with Jack more about his views on Ben failing to properly look after his children when one of the daughters slips off the roof almost getting killed. Through close up shots we see Ben realising hat he's done and trying to take it all in. In the scene between Ben and Jack, there is a clear difference between them. They have different views and are shown to be different with their clothing. Ben dresses informal with his bright, unbuttoned shirt while Jack dresses formally with his buttoned up shirt and tie. Although we reason with Jack more, Ben is still doing a good job of teaching his children. An example of this is when he calls his daughter down to talk about the bill of rights. The uncle's children can't explain it well but the auntie still praises him showing the modern American family have low expectations of their children. Ben doesn't just get her to state facts but explain it in her own words which goes to show what a great teacher he is.
Religion is explored through the movie like Ben's wife is a Christian but changed to a Buddhist when she gets married to him and when the wife dies Ben say's the last thing she would of wanted was a Christian burial. When Ben say's they don't make fun of anyone, his daughter reminds him that they ''make fun of Christian's''. Both Leslie and Bo have a love of Bach whose music is supported by Christians. Ben also comments about how they don't celebrate Christmas and makes a remark about the Christmas elves.
A social issue raised in the films is the family's social norms. One of these is when the family makes Bo, the older brother kill the deer in a green camouflage. When we first see this, we are too believe he is a savage but soon realise he is part of a family who present this 'animalistic' behaviour every day. Another example of a social norm presented here is the ritual the father holds to make Bo a man for killing a deer. They also celebrate their own holiday that only that family know about and on this day is when the father gives his children weapons which is there normal. This eventually leads Jack who is the granddad to want full custody over the children after Bodivan want's this and the daughter almost breaking her neck after falling of a roof.
Rellion has a desire throughout the film to be a normal family and be like the rest of society ''Why can't we celebrate Christmas like the rest of the world''.
Parenting- They also decide that they want to stay with their Father despite him saying ''I'll ruin your lives''. We reason with Ben as we've seen how careless he can be when his daughter fell off the room just like how earlier we reasoned with Jack about Ben failing to raise his children properly.
Gender equality- The children all perform the same tasks and taught the same skills so roles are not gendered throughout the film. However, the closing scene suggests that greater integration into mainstream society may change this as Zaja is feminised through her clothing.
The film encourages identification with Ben as when he hallucinated Ben, we see her through POV, close-up shots. However, we later align with Jack when he talks about Relian's broken arm being child abuse and later on when Vespyr falls off the roof.
Critique of contemporary American Society- One of the films tagline is 'Americans are over medicated and under educated' and when the children enter mainstream society they comment on the obesity of others around them, ''everyone is so fat'', ''are they sick?''. Jack's can't explain the Bill of Rights which shows that traditional education is failing them while alternative education for Ben's children is much more effective. The. Auntie still praises her children showing the modern American family have low expectations of their children.
Captain Fantastic has a closed ending as in the final scene, we see them all living happily on the farm and are now all at school and studying academic subjects like quantum physics, literature but physical fitness is still valued highly. The tyres are removed from the caravan which shows that they're here to stay for good.
Anti-authority messages throughout the film including the scene where the children pretend to be a christian cult to disconcert the police officer. Recurring quotes in the film include ''Power to the people'' and ''Stick it to the Man''.
