The premiere season of Showtime's "Yellowjackets" is a thought-provoking and unsettling exploration of trauma, survival, and the lasting impact of a catastrophic event on a group of high school girls. The series masterfully weaves together two timelines, expertly juxtaposing the team's harrowing experience as stranded survivors of a plane crash in the Canadian wilderness in 1996 with their lives 25 years later, as adults struggling to cope with the aftermath.
