Rampant Reviews & Ratings
Critics gave Rampant 62% on Rotten Tomatoes, and IMDb users rate it 6.3/10. Our Echo Score gives it 69/100, strongest in sensory experience (90) and weakest in story & flow (45).
Rampant Echo Score Breakdown
The film delivers a striking visual presentation but struggles to maintain consistent narrative momentum. Critics and viewers praise its detailed period production design and gruesome action sequences, while noting uneven mythology, predictable plot points, and a languid first half. The direction of visceral set-pieces provides energy but is offset by muddled pacing and superficial character arcs. Although the medieval setting and genre blend offer occasional novelty, the overall experience remains uneven. Ultimately, Rampant offers compelling moments amid persistent structural weaknesses.
Our own 0–100 rating, built from five aspects: art, character, story, the sensory experience and how well a film rewatches.
- Art & Craft 80
In terms of art and craft, Rampant excels in its visual presentation but shows occasional inconsistency in execution. Reviewers highlight the film’s elaborate period production design, vivid color palette, and dynamic action editing. Critics commend the cinematography for capturing the gruesome details of each set-piece, though some note abrupt tonal shifts in mythology sequences. Overall, the film offers striking visuals tempered by an uneven integration of stylistic elements.
- Character & Emotion 70
When it comes to character and emotion, performances are solid yet emotional depth fluctuates. Viewers appreciate the leads’ committed acting and some engaging subplots that develop supporting figures. However, the large ensemble often lacks distinguishing traits, and several emotional beats feel forced or underdeveloped. In summary, the film delivers competent performances but struggles to establish consistent emotional resonance.
- Story & Flow 45
In terms of story and flow, Rampant is hampered by a predictable and at times disjointed narrative. While the medieval-horror hybrid introduces a novel context, critics and audiences point to a slow first half, assorted plot holes, and lapses in mythological coherence. These issues undermine engagement despite intermittent action peaks. Overall, the storyline offers limited momentum and originality.
- Sensory Experience 90
When it comes to sensory experience, the film delivers a strongly immersive atmosphere. Critics and viewers praise its unsettling sound design, a driving musical score, and atmospheric soundscapes that enhance tension. The visual style is marked by vivid gore effects, restrained color grading, and meticulously framed action sequences. In conclusion, Rampant offers a powerful sensory impact that anchors its horror elements.
- Rewatch Factor 60
In terms of rewatch factor, Rampant provides moderate repeat appeal for genre enthusiasts. The visceral action sequences and period setting may invite another viewing for their spectacle, but the predictability of the plot and uneven pacing diminish lasting interest. While gore aficionados may revisit key scenes, the overall combination of narrative weaknesses limits the film’s enduring replay value.

In the Joseon era, the court is steeped in tension as nationalists view King Lee Jo as a puppet of the Qing dynasty.

But war Minister Kim Ja-joon, a formidable influencer at court, uncovers the scheme and twists it into a much darker narrative of rebellion.
