Reporting on this a little late, but saw Parasite a few weeks back.
Hadn't seen it before the Oscars and was rather shocked it took home the top prize ... that is, until I saw it myself. Brilliant film and easily my pick for top choice of the best picture winners this decade, edging out Moonlight. It's a film with essentially two diametrically opposed genres that somehow mesh perfectly, and has something unique, refreshing, and frankly poignant to say about income inequality.
And that's not simply coming from me. My wife is my personal "canary in the coal mine" when it comes to movies. She doesn't like cinema generally and typically doesn't have the patience for subtitles. She, however, absolutely loved Parasite and was still talking about it a couple days later.
Being that she is married to a cinephile, she's begrudgingly sat through her fair share of best picture nominees with me. The only ones to have ever truly impressed her have been Parasite, Moonlight, Argo, The Theory of Everything, Lion and, of all things, Mad Max: Fury Road.
