Samurai Cop is of course an all time classic. Dialogue writers of today could take a lesson from it's nuanced delivery of prosaic conversational interplay. It's a crime against humanity that they didn't win an Oscar.
It always reminds me of another underrated masterpiece, "garbage day", a somewhat self contained interlude in the tightly woven plot of "Silent Night, Deadly Night 2"
This film was important for me personally. I used to run out my front door screaming "what the hell is all that noise out there" every time someone walked quietly down the street in front of my house, but after seeing this, I reconsidered my approach, and just left random pedestrians alone.
I have not seen "Bitch Slap", but I fear for the sanity of the foley team. You typically don't have to put literally hundreds of sounds in a two minute clip, they must have been up for days.
