Annihilation, Alex Garland’s follow-up to his film Ex Machina, was one of the most exciting and divisive films of the year. The science fiction horror movie led by Natalie Portman featured one of the most impressive final acts in a movie this year, helped by a truly awe-inspiring score from Ben Salisbury and Geoff Barrow. The score predominately features heavy synth tunes, but weaves in dissonant strings and guitars to help create a deeply unsettling sound for the movie.
