FULL SPOILER-FREE REVIEW @ https://movieswetextedabout.com/boy-kills-world-movie-review-a-very-bloody-good-time/
"Boy Kills World finds its stage when it focuses on the cool stunts and explosion of unrestrained action that will certainly win over genre aficionados.
The revenge premise never quite flies off narratively, remaining a thematically superficial, undeveloped story, but the numerous sequences of violently choreographed fights are entertaining enough to please the majority of the audience. The layer of humor fits the light tone, but beware of the complete uninhibitedness regarding the doses of blood, ruthlessness, and creative use of everyday items for combat.
The standard recommendation for a weekend without plans."
Rating: B-
