Oh, Rocky! It's never going to get any better that this. It looks great, it sounds great. Fox have finally given 'The Rocky Horror Picture Show' (1975) the A/V love and respect it so richly deserves. They've made a few $ from this one over the decades and it was obviously time to give something back.
It couldn't really look an more pristine, the print transfer is fabulous, colours positively pop from the screen, solid blacks and NO trace of DNR. The grain that is visible, should be visible. Given the age of the of the film, the 70's stock used to shoot on, it all holds up remarkably well. There are slight issues around the quality of a few shots that incorporate optical's but nothing of any real concern, besides, these minor issues cannot be avoided. The audio is also given a real boost and is unlikely to sound better. Extras are plentiful, some new to Blu ray, others ported over from the previous DVD release.
If you've never seen the film -stop wasting time reading this and buy it immediately! If you already own a copy on DVD, go for this Blu ray upgrade, superior image and audio quality, this transfer is superb!
