Having now seen the first three "Friday" films on Blu, I have to say that this is darn close to being the best. Part II maybe just edges it for picture quality, but the original is surprisingly sharp, with night-time scenes very well managed and no objectionable grain levels, for my money. Colours are occasionally a little overcooked, as in the late diner scene, but then the seventies were just ending and perhaps they really were wearing those colours? That aside, colours and contrasts are generally good, with fairly solid black levels. This film really puts Part III to shame in terms of picture quality.
The soundtrack is also quite impressive for the age. Forceful and sinister, particularly in the last half hour. Dialogue is maybe occasionally a bit light-sounding, but on the whole the True HD 5.1 soundtrack does a terrific job, with respectable surround and subwoofer effects. To compare it with its great rival "Halloween" of which this film was something of an imitation: the sound quality is comfortably better, the colours are richer, and sharpness is also somewhat better.
The plot remains the great ace in the sleeve, with a magnificent twist and a truly shocking ending. The original film has still not lost its power to generate suspense and make you jump.
A really great transfer of a much loved Classic, albeit a classic indebted to "Halloween" and, in an inverted way, "Psycho".
