I was expecting HLBN to be a dark, noir-ish serial killer film - and at times it is, but more often than not it's a comedy... sometimes a very dark comedy, sometimes a very silly comedy about a late night radio show host (Sylvia Chang), a serial killer with issues about white stockings and two cops who put the "stupid" in... err... "two really stupid cops". The plot hinges almost entirely on them being incompetent and acting inappropriately, in the grand Hong Kong tradition. Sometimes it's quite funny!
