If the original version was available on the bd, fans wouldn't care much about the tinkering. Even Hammer's own Marcus Hearn agrees. Quote from the Cathode Ray Tube blog review:
Putting the ethics of whether you should go back and revise or enhance films to one side, I believe not including the original, restored version without the enhanced effects on this release is an error of judgement. Both versions should have been on the disc to satisfy fans, old and new, and to quote Marcus Hearn, fulfill 'the efforts that have been made to present [these films] as most British audience-members would have originally seen them.' Clearly they never saw the film with CGI clouds, smoke and water and I'm sure many of us would like the choice to see the restored film as such. http://www.cathoderaytube.co.uk/2012...rides-out.html
