I think a lot of reviewers are being hung up on pronunciations and such as an overall reflection on the production, and that is very close-minded. Maybe living in Canada has given me enough exposure that those are just people speaking English with a heavy French accent, and is no way a reflection on their intelligence or expertise. If you want to watch a show that involves international crimes of this nature you need to temper your expectations over minutiae like that as it's unlikely an American production team would ever be outward looking enough to report of the crimes this series does.
I'd say the production values were par for the course or a bit worse, and they pulled off the premise of showing crimes with some sort of occult angle, and this is where people are being unnecessarily offended almost it seems, as the series' use of the term occult reflects where the average person off the street would hear the word and the first thing that would pop into their thought is "occult". The series didn't seem to me to be making any moral judgments at all, so those complaining about this are setting up straw men to attack.
And with things like D&D, when you play it it does put you in a mindset where you collaborate closely in a highly calculated way, it's how you play effectively, where that vast majority of people wouldn't be affected negatively at all by that. But the person with antisocial personality disorder (and any highly suggestible people around them) could be very negatively affected by learning to plot out killing something and the rush that comes with that in-game, being a hunter could trigger someone in the same way, and it's a sad statement that D&D carries a stigma of "occult" in the public imagination and hunting doesn't, but blaming the producers for this seems very odd to me.
