Everyone decries "all-sex porn", the pervasive but lucrative filler that has dominated video and latterly the internet since the cult of amateurism took over more than two decades ago. This misleadingly titled film displays the obverse; it's even worse when a plot is introduced and then so badly bungled.Told in flashback a la film noir procedure, The Sins of Sandra is not about Sandra but rather Julie, pouring out her dreary tale of how she ended up being accused of murder. The victim Johnny discovered her stripping at "Dirty Sally's" in L.A., brought her to Las Vegas and dragged her down to his level. Title personage Sandra is an oriental gangster lady who it turns out framed Julie.This embarrassing assemblage of footage qualifies as a film by only the dictionary definition. The details of the scam & frame up are presented as part of Julie's endless flashback, yet she was clearly not privy to them. Not that I expect even a minimum film-school training for pornographers, but these blokes include at will filler sex scenes that have nothing to do with the story, and even end the picture with a complete non sequitur scene guaranteed to puzzle the most attentive viewer.Winner of the worst acting sweepstakes has to be the critter playing Johnny -he can't recite or improvise dialog to save his ass. Close second is Suki Yu as Sandra -she demonstrates how to overact and non-act simultaneously -it's difficult but made easier if you have trouble with the English language in the first place. Despite the title, Suki as Sandra has a tiny, tiny role and does not participate in any sex scenes. Film's only attempt at wit is the editor being credited as "Ken I. Cuttem". Hardy-har-har.
