"Let's ruin our war drama movie idea and add some zombies" Frankly, it's quite funny how more negative sided reviews gets downvoted here. The movie itself, to put it in a nice way, is somewhat mediocre at best. You can understand that for the Spanish people it may have a niuance with historical sentimentality, but that does not change anything in a value of the movie. Looks like it had a chance to be a decent war drama, until somebody just thought of putting zombies in it. The acting was okay, cinematography was also alright. But... Boy oh boy, the nowhere leading script, majorly awkward and rushed dalogues, chaotically incorporated intercaltural references, basic logical errors. So, all in all, we have some low-budget generic movie, which is not really an ideal option even for binge-watching.
