All of Kurosawa's (not that one) work is pretty much brilliant. Cure, Creepy, Tokyo Sonata, Journey to the Shore kisses fingers what a genius.
I think my favourite thing about him is how placid and still his camerawork is, and how his ghost stories all seem to have this element of magical realism to them - like the room decaying in Journey to the Shore, or the sealed up rooms being opened up in Pulse.
He's also very good at denying the viewer access to spaces they want to see the stand out example of this for me is in Cure (his best I'd say) where he uses oblique angles in rooms to cut off your line of sight between two characters, or in the hospital basement where he refuses to let you see the antagonist moving towards the nurse until he cuts to him right in her face - far better than any music stab jump scare.
One of my last essays for university was a look at Psychospace in his Cinema, how his films use these cave like and recessed spaces to explore the trauma of the second world war. Heck, even my dissertation paid lipservice to Pulse even though it was about Serial Experiments Lain and Psycho-Pass.
Wheww, rambling. Anyway, Cure, Pulse and Creepy are three excellent and largely slept-on horror films.
