The Red Panther

As others have stated this had a Giallo feel to it but man did the shitty humor ruin this thing for me.

Crazy Hong Kong CATIII movie that resembles Italian giallo, just more off the hook. It's a story about Mario-from-Bros-went-bum looking mumbling policeman (the ongoing joke is that he has potentially fatal, so the doc claims, hemorrhoids), who tries to solve serial killer case. The plot goes from toilet humor, to gruesome (and unexpectedly well filmed) murders to almost surreal effect. The ending is a shocker. Trashy but mesmerizing freaky film. Rating it high, because it managed to surprise me.
