The Host is the film adaptation of the novel with the same name from Stephanie Meyer, the author of Twilight. The Host tells the story of a future where the world is perfect. However, perfection is not exactly how you would imagine it.
In the future, alien 'Souls' descend, taking human hosts in order to purify and cleanse Earth. Despite the surface benefits this brings, the deeper truth is quite different and all is not as it seems. For that reason, there are pockets of resistance battling against this omnipresent force.
One survivor and member of the resistance, Melanie (Saoirse Ronan), is captured and becomes a host to an alien Soul named Wanderer. The story that unfolds shows their journey, as they grow together and develop a friendship and mutual respect for one another.
After escaping, Melanie and Wanderer journey to the safe haven where Melanie's family are living with other human survivors. They eventually reach their destination with a stroke of luck, but once they arrive drama ensues. The people see Wanderer as a threat, and struggle to trust her.
Eventually, through the actions of Melanie's uncle Jeb and Jamie, the community come to trust Wanderer. This leads to Wanderer, soon nicknamed Wanda, to establish herself in the community in a unique way. However, not everyone is happy about Wanda joining the close-knit community and with The Seeker on Wanda/Melanie's tail, the two minds in the one body face an uphill battle for their survival, and that of their loved ones.
Ronan plays the strong-willed Melanie and equally impressive character Wanda with ease and manages to easily balance her dual roles. Elsewhere in the film, Max Irons and Jake Abel round out the cast as Jared and Ian, respectively. Melanie loves Jared, and in fact the sole reason she returned was to see him and her younger brother Jamie again. Meanwhile, as Wanda develops feelings for Ian, one of the few who accepts her for who she is.
Overall, The Host is a film that makes you remember all the things about the world that are special and are worth trying to protect. It is easy to become invested in the characters and storytelling, as both manage to encapsulate viewers with relative ease.
