It’s hard to say that this film succeeds. The central idea feels foolish, attempting to combine elements of "Train to Busan" and "The Exorcist," yet falling short with both inspirations. William delivers a decent performance, however, the rest of the cast seems to be having difficulty rising to the challenge. The special effects are noticeably weak, as is the cinematography and sound design; the direction feels rushed, and the actors chosen aren't particularly well-suited for their roles. While there’s evidence that some investment was made in production values, preventing it from being a complete disaster, ultimately, this isn’t a worthwhile film.
