Movies like The Ballad of Jack and Rose

1986. Jack Slavin, an engineer by trade, and his mid-teen daughter Rose Slavin live in virtual isolation on what was once a commune that Jack and a group of others built in 1968 on sparsely populated Marsh Island off the U.S. east coast. Rose's mother abandoned them when Rose was five. Jack has passed to Rose a sense of ecological preservation, placing them at odds with Marty Rance, who is building a housing complex on the island on a wetlands. They are able to live this life on the commune property in their ecological bliss due to a sizable inheritance, Jack who will occasionally take out his checkbook in order to solve whatever problem he may be facing. Jack also took Rose out of school when she was eleven as he didn't believe in what the traditional school system was teaching. Their quiet life together is threatened by the fact that Jack has a heart condition which will probably kill him sooner than later. Wanting to ensure that Rose is taken care of after his passing, Jack makes the unilateral decision to ask Kathleen, a woman who he has been dating for four months, to move in, along with her two mismatched sons, half-brothers Rodney and Thaddius who don't much like each other. Jack tries to pass Kathleen and her sons to Rose as "an experiment" and the three of them solely as "guests", rather than the reality of them truly moving in. Kathleen, who had never met Rose before, agreed in her savior complex and in truly loving Jack, knowing fully the reasons for he asking her. These changes deeply affect Rose, who has had Jack all to herself for the better part of her life - she who threatens to commit suicide after Jack dies - and comes at a key point in her own life as she is just starting to explore her sexuality.
