"The Haunting of Sharon Tate"

Whilst I've not seen all the movies you've named here, the ones I have - for me - don't really align with this one for purposes of comparison.

WOLF CREEK is largely fiction, albeit inspired by backpacker disappearances/murders in Australia. The characters are fictitious and events are not documenting actual recorded cases.

TCM is similar, with one character simply inspired by Ed Gein but not an account of any recorded case and a plot that is fiction and not recreating actual events.

SOME LIKE IT HOT for me, hardly exploits the Valentines Day Massacre - the event simply serves as the backdrop for what otherwise is a slapstick, romantic comedy.

The Kray film that I've seen, is very much a biopic that tries to paint a picture of the background and environment that led to the twins rise in the London criminal underworld. It attempts to tell a story based on a time and place where they operated with factual accounts recorded from the period. I'm sure some dramatic liberties are taken here and there but in essence the story remains largely fact based and I would say does not veer into exploitation.

Jack the Ripper and Lizzie Borden are mysteries that have become part of folklore. Any movies about these cases are forced to manufacture detail because we don't have full facts. I doubt they exploit the victims. Tours of the sites are part educational and yes - perhaps spawned out of morbid curiosity - but again, I'd say they are more about enlightenment than sensationalising events at the victims expense.

As for Marilyn Manson and Kasabian - yes, I do think it was exploitative of them also to take these names to promote themselves in the field of entertainment. I think it was a cheap way of drawing initial attention to themselves on their journey to fame. I feel just the same when I see Rob Zombie appearing publicly in a Charles Manson T-shirt. Regardless of any talent they may have, or the quality of their music (I've never listened to any of the three), I feel their choices of action in those instances are juvenile, questionable and send out a rather dubious message to their fan base or intended audience.

Am I saying I'm right about all this?
Not necessarily......but this is genuinely how I feel - particularly about this new Tate film and how it's coming across.

And while I can't speak for anyone else, I can give full assurances that my knickers aren't in a twist about any of this!
It's simply a viewpoint.
