Visually, the series does well creating a dark, tense atmosphere, especially for Latin American standards. PRODU+1 The zombies themselves are decently creepy, particularly when the narrative leans into their mutant nature. FormulaTV
However, character development is uneven: while Alonso is compelling, many supporting characters—especially women—don’t receive enough depth. FormulaTV Some subplots (like between Marroquín and his son Lucas) begin strong but lose momentum as horror elements take over. FormulaTV

One major issue is pacing – the buildup feels sluggish for much of the early episodes and the fusion of genres (narco thriller + zombie horror) sometimes clashes rather than complements. FormulaTV+1

Dialogue and acting are hit‑or‑miss; there are moments of good tension, but also scenes that feel formulaic. Rotten Tomatoes+1 On the plus side, the show’s ambition is clear: it doesn’t shy away from raising questions about corruption, border politics, and the ethics of experimentation. infobae+1

Overall, S.O.Z: Soldados o Zombies is an entertaining ride if you like zombie horror with a twist of narco action and don’t mind a bit of messiness. Its strengths in atmosphere, concept, and moments of tension are enough to recommend it, though it falls short of being truly great.
