She dies by suicide while undergoing treatment and Ben learns that her father Jack Bertrang plans to hold a Christian burial despite Leslie being a philosophical Buddhist who abhorred religion.

After this, some of Ben's children start to doubt him and his parenting skills, with his second eldest son and middle child Rellian accusing him of failing to treat Leslie's mental health, and eldest son Bodevan accusing him of not equipping them for the real world, showing him acceptance letters from several top Ivy League colleges to which Leslie had helped him apply.

The final scene shows the school-age children eating breakfast around the kitchen table with their father, waiting for the school bus to arrive.

The site's critical consensus reads, "Captain Fantastic's thought-provoking themes—and an absorbing starring turn from Viggo Mortensen—add up to an above-average family drama with unexpected twists.

[26] Alonso Duralde of TheWrap gave the film a positive review, saying, "The movie really belongs to Mortensen, who allows Ben to be exasperating, arrogant, and impatient but also warm, loving, and caring.

He's a tough but adoring father, a grieving widower and a passionate defender of his wife's final wishes, and Mortensen plays all these notes, and more with subtlety and grace.

"[27] Peter Debruge of Variety gave the film a positive review, saying "Boasting half a dozen impressive youth performances alongside a leading role that takes full advantage of Mortensen's own sensitive, back-to-nature spirit, Captain Fantastic easily ranks among the most polished and relatable of this year's Sundance offerings.

"[28] A negative review from The Guardian's Peter Bradshaw states, "There's a meaty whiff of phony-baloney in this fatuous and tiresome movie, replete with forced emotional crises and wrong notes, topped off with an excruciatingly unearned, sentimental ending.

It's a low-cal version of Peter Weir's 1986 movie The Mosquito Coast, starring someone who is essentially a cross between Charles Manson and Captain von Trapp.
