Colony doesn’t stray far from the familiar zombie movie formula. Although the writing demonstrates intelligence, it struggles to set itself apart from other films in the genre beyond presenting a concept of a zombie hive mind. That being said, it's still potentially worth seeing if you enjoy this type of story. The performances are strong; the characters feel well-developed and react realistically—both positively and negatively—to the unfolding catastrophe around them. The action sequences are also well done, delivering plenty of thrills with zombies but lacking in truly frightening moments, supported by competent fight staging and visuals. Ultimately, Colony doesn’t introduce anything groundbreaking, but the script provides enough intrigue and excitement to justify watching it.
