I didn't realize he also did 'The Host'. I know that he did a film called 'Murder & Snowpiercer', which is about South Korea's first serial killer (apparently) and comes highly recommended.
'Parasite' is absolutely incredible. Really fantastic filmmaking at its best.
Sadly, sometimes it's that lazy attitude of not wanting to read subtitles.
It's well worth your time....within 5-10 minutes you don't even notice you are reading and able to look at the imagery as well. Hopefully it is shown at a cinema near you. Well worth seeing on the big screen.
