I don't believe in-fact I am almost certain that this will be anything like the normal You-tube crap are like, and would be done very tastefully with a lot of talk on modern exploration and rescue. Dan Hartley is a professional director, who is Yorkshire born and bred and done some very thought provoking stuff in the past.
I am not sure I understand the original post when they seem to suggest that the memory should be forgotten by "leaving the memory in peace"? Surely that's the last thing that should happen? Because if we do, then should we also then say, do away with the all the world war 1 and 2 films and documentaries, heck why not cancel the poppy parade itself?
Provided its done respectfully, and tells the stories of these great pioneers of the past, then why should it not be done, lest there exploits be forgotten forever. I know if it was me who drowned in there, I would not want to be forgotten.
