No, it'S not the film grain which is the issue. The whole image looks out of focus. It doesn't look sharp at all. Ghostbusters on BluRay is very grainy thanks to the cheap film stock it was shot on but that does look sharp.
Maybe it's down to the digital clean up or they just rejuiced the grain level and I think the original master was in a bad state like the original master for jaws was.
