A low-budget film, but where everyone tries to do the best they can.
Generally, I don't like films with the living dead, although I've seen several in recent times. This was one of them. Out of nowhere, the characters are thrown into a total apocalypse where people become zombies that they don't know how to kill. The protagonist is a young nurse, who immediately loses her entire family in the first moment. That makes us instantly like her. From then on, we hope that she will save herself and find other survivors to form an alliance with, which inevitably happens when she finds a shopping mall.
Zack Snyder directs this film and delivers a very competent and well-made story, which manages to captivate the audience with a convincing and structured story. The film is, moreover, a remake of an original by George A. Romero, but it is really worth seeing this film for what it is, without comparisons. Technically, the film was well edited and has good sets, costumes and makeup, and a pleasantly stable pace that doesn't leave us thinking about things too much. Of course, there are obvious clichés and logical flaws in all of this, such as the fact that some things never stop working (running water, electricity, etc.), but I forgave these problems.
The cast doesn't have any particularly big names, perhaps it was a conscious and deliberate decision to make this film with lesser-known actors, with whom everyone could identify more easily. Sarah Polley is the protagonist and does a very decent job, as do Ving Rhames and Michael Kelly. It is noted, however, that the entire film was made with very low budgets and that there is some amateurism and improvisation in the work of the cast and technical team. Still, weighing things up, it's not a bad film and everyone did the best they could do.
