I'm not fond of Persona in the slightest, but its totally because of my association with a certain profesor when I watched it... Anyways, lots of one I haven't seen on huluplus of his. Winter Light will be next, thanks.
Also, doing a Three Colors rewatch soon with a friend who has not seen any of them. Recommendations on Kieślowski aside from those? The Double Life of Veronique is the only title I recall looking at his filmography.
