I watched Parasite on Amazon Prime last night it's only £1.99 for a two day rental (£4.99 on Apple) an amazing film, one of the best I've watched for a long time, no idea how it won best film at the oscars as it's not your typical big budget American type of movie but definitely a worthy winner.
I'd rate it right up there with In The Mood For Love, by Wong Kar-Wai, which is one of the best movies ever made IMO and also his ChungKing Express, Parasite is a completely different movie from both of those films but the acting and cinematography and the story is just as good. I loved it.
Highly recommended.
