I probably wouldn't categorically object so much to the porn-parody genre if in fact these exercises in plagiarism were funny - after all, that should be a prerequisite to their existence given that "parody" is what makes them legal. But this imitation of John Landis's classic movie (he of course started off his career in the mainstream parody genre) is not as egregious as Gus Van Sant's ripoff of "Psycho' but still in the same ballpark.
The SPFX are lousy, as would be expected with low-budget porn, and the frequent second-unit footage on London locations is too obvious and touristy to give the patina of a real movie.
Only saving grace for me was the casting of authentic UK talent, albeit mainly dropouts from the Brit Porn scene who had relocated to Chatsworth years ago. Exception is lead femme Lexi Ward, who did not flee her home country (IMDb must have erroneously used a Default setting to give USA as her birth country in its listing). She's a most sexy nurse opposite hapless Yank turning into a lycanthrope Richie in the title role. But sexier is the Welsh bombshell Sophie Dee as a bustier fellow nurse, fortunate to be paired with the big cock of Ben English.
Dane Cross's sidekick for Richie is a bore, and the mimeographed scenes unfold listlessly in Jim Powers' Cliff Notes approach.
