I've watched the first twenty or so minutes of this and, for the most part, the audio track is wildly out of synch with the visuals. It's apparent even in the first dialogue-free scenes when a falling trapdoor produces a bang almost a second too late. The scenes in the pub are a frame or two adrift but, by the time the travellers reach Castle Dracula, things are so out of synch it's like watching a dubbed foreign film. The problem is the same on both the Blu-ray disc and the DVD, so the fault is in the master.
I really want these Hammer Blu-rays to succeed, but this particular product is substandard. Was no quality control done at all? Studio Canal need to do the decent thing: recall and replace these discs. They also need to put in place procedures to make sure future titles are unaffected.
UPDATE (7/3/12): Hammer/Studio Canal have announced a replacement scheme. Once I have received the corrected disc I shall alter this review accordingly, presuming that the fault has been fixed.
