Totally Killer (2023) delivers a fresh and entertaining blend of horror, comedy, and time-travel sci-fi that revitalizes the slasher genre. The film follows 17-year-old Jamie, who finds herself accidentally transported back to 1987 after the infamous 'Sweet Sixteen Killer' resurfaces in her present day. With the killer's original murder spree about to begin, Jamie must navigate the neon-soaked, hairspray-heavy world of the 80s to prevent the tragedies that will haunt her hometown for decades.

Kiernan Shipka shines as Jamie, bringing both comedic timing and genuine emotional stakes to her role as a modern teen utterly out of place in the past. The film cleverly contrasts contemporary sensibilities with 80s nostalgia, creating hilarious cultural clashes while maintaining genuine suspense. Director Nahnatchka Khan balances horror elements with sharp comedy, creating a tone reminiscent of Happy Death Day meets Back to the Future.

The mystery elements keep viewers engaged as Jamie races against time, and the 80s production design is both authentic and delightfully exaggerated. While the 6.5 IMDb rating reflects some formulaic elements, the film's inventive premise and energetic execution make it stand out. Totally Killer succeeds as both a loving homage to 80s slashers and a clever commentary on how we remember—and sometimes romanticize—the past. For anyone seeking a fun, fast-paced horror-comedy with heart and humor, this 106-minute ride is thoroughly entertaining.
