Gymnopedie’s review published on Letterboxd:
Naturally, there are so many horror movies released each year that it's difficult to see them all. Subsequently, some great horror films have, and continue to, slip under the radar. Mutants is one of such movies. The breathtaking French countryside that serves as a background to a deadly virus that spreads through France, that turns its unfortunate victims into unstoppable flesh-eating mutants, but unlike other Zombie movies, it differs, in that it offers its victims the cruelty of hope - a long, slow and painful transformation (that can only be truly compared to that of I Zombie: The Chronicles of Pain and The Fly) to full-blown mutant, by means of loss of biological functions and decay - in the most terrible of ways.
The story centres around a deadly and terrifying infection that has transformed the majority of people into raging mutants. Marco (played by Francis Renaud) and Sonia (played by Hélène de Fougerolles) - (who both give wonderful performances) are a young couple, Sonia, is a medical professional and Marco is a paramedic, who are both escaping the monsters and trying to fight their way to a military base. Marco himself becomes infected in an attack, leaving the pregnant Sonia, who must defend herself against one of these mutants - who is also the man she loves. She feels that Marco can be saved and she truly believes that she can cure him of the infection. She is fighting against time...
Mutants is claustrophobic, atmospheric and has tons of gore and blood, often disturbing and sickening, with scary looking mutants - but what do you expect from a Zombie flick? There is more to this movie than just blood and gore. The cinematography is stunning. For all its action packed sequences, reminiscent of The Walking Dead, this is effectively a love story, wrapped in a morality tale, inside an Zombie movie. It does, however, share similarities with other movies in this sub- genre, namely, Day of the Dead and 28 Days Later. That being said, it is fairly unique to the other movies, in that, it is psychological in nature, ultimately it is a unique inclusion, to an exhausted sub- genre. It certainly makes my Top Ten Zombie movies!
