"Raped by an Angel 4:The Raper's Union" features three rapists led by Ben Ng of "Red to Kill" fame.Ng plays an ex-CIA worker who uses the latest in miniature technology to peep and prod into the lives of his victims,notably lovely novelist Suki Kwan.He and his two rapist friends form a close union to rape as many young Chinese girls as they could."Raped by an Angel 4" is a cheesy and mildly amusing exploitation flick that offers a little bit of sleaze plus some clever jokes.It also has Anthony Wong in a small role as the ancestor of rapists.There are some moments of rape and terror,but there is not enough sleazy exploitation or nasty violence for my liking.Overall,I prefer watching more serious Cat III fare over this one.My rating:6 out of 10.
