Sissy (2022) is a sharp and surprising genre-blend from Australia that deftly mixes social media satire with brutal revenge thriller elements. The film follows Cecilia, a wellness influencer who projects a perfect life online, as she unexpectedly reunites with her childhood best friend Emma after a decade apart. When Emma invites Cecilia to her bachelorette weekend at a remote cabin, Cecilia finds herself trapped with her former high school bully, setting the stage for a tense and bloody confrontation.

Aisha Dee delivers a standout performance as Cecilia, perfectly capturing the character's fragile persona and hidden rage. The supporting cast, including Hannah Barlow who also co-directed, creates a believable dynamic of adult friendships strained by unresolved adolescent trauma. Directors Hannah Barlow and Kane Senes skillfully balance dark comedy with genuine horror, using the isolated cabin setting to amplify the psychological tension.

What makes Sissy particularly compelling is its timely exploration of social media facades and how past traumas can resurface in adulthood. The film transitions smoothly from witty social commentary to visceral thriller, keeping viewers guessing about how far Cecilia will go for revenge. With its clever script, strong performances, and effective blend of humor and horror, Sissy offers a fresh take on the revenge genre that's both entertaining and thought-provoking. For fans of smart horror-comedies like Ready or Not or The Babysitter, this Australian gem is definitely worth watching.
