Note: I have not seen the entire Park Cinematic Universe (notable omissions: KEN PARK, WICKER PARK, GORKY PARK, CARNAGE PARK, PARK ROW, THE PARK IS MINE, and PANIC IN NEEDLE PARK), but everything I have seen has at least been pretty good, and if I hadn't had a front row far left seat for GOSFORD PARK in reaching distance of the screen it might have been higher.
And don't go suggesting Chan-Wook Park's films belong here. That would be silly.
