Some comic book films (and films in general) are rated a 15 in the UK despite their PG-13 rating in the US. ‘Suicide Squad’ and ‘Venom’ are two examples that I can think of. I can also remember that there were calls to get ‘The Dark Knight’ shifted to a 15 in the UK because of the violence back in 2008. So no, the R/15 rating isn’t dead here.
Also, this just cropped up:
I’m laughing at the whimp that wrote this; they most certainly not’ve survived watching the original ‘Blade’ films if they think that the new Suicide Squad film was “too gory” (no I’ve not seen it but I think I’m tempted to now). We really have been dumbed down. 12a’s/PG-13’s would’ve been considered teen films when I was growing up. Not the family friendly nonsense that we get now. Same with the R/15 rating. An 18 rating was considered and adult film.
