One of only a handful of scattered rebels is Melanie Stryder (Saoirse Ronan), on the run from the invading race’s agents with her younger brother Jamie (Chandler Canterbury). Held captive after a near-fatal fall, Melanie is assimilated by the planet’s new dominant species before being renamed ‘Wanderer’ (‘Wanda’) by arresting officer-turned-interrogator The Seeker (Diane Kruger). Coerced into sharing Melanie’s past memories, including the identity of lover Jared (Max Irons), Wanda begins to question the morality of her kin’s occupation. As Melanie attempts to retake control of her own body, the two entities escape their confines and head into the desert to search for Jared and the last remnants of humanity.
Whilst by no means a complete disaster – Ronan makes the best of the role she’s given, despite some grating ‘voice in my head’ back and forth dialogue – there’s precious little on show here to appeal to audiences that aren’t acquainted with Meyer’s source material. Also unlikely to win the favour of many sci-fi fans due to its unimaginative setting and dull production design, The Host plays out its girl-meets-boy, alien-girl-hybrid-meets-other-boy (Jake Abel’s Ian) ménage à trois with minimal fuss – providing, as a consequence, minimal enjoyment.
