The writer-director team of Chris Cullari and Jennifer Raite (making a strong feature filmmaking debut) don’t disguise the connections between Skylight and NXIVM. As they flee the group’s charismatic leader, Seth (Chris Messina), the starving fugitives begin to hallucinate - and then to doubt each other’s motives. If you’ve watched any of the documentaries about the NXIVM cult, you’ll recognize a lot of the details in the intense escape drama “The Aviary.” Malin Akerman plays Jillian, who as the movie begins is trudging through the desert with Blair (Lorena Izzo), a woman she recruited into Skylight: a wellness organization that manipulates its members through deprivation and abuse, NXIVM-style.
