Crazy how this got only a 15 cert in UK

If ever there be an 18 movie it should be this, not just the extreme violence but the unnerving vibe of it and the dealing with serious mental health issues (also it feels like it could be abit of potentially dangerous movie for a very young person to watch), id put it alongside Fight Club and American Psycho, and Death Wish which were all rated 18 in UK. I guess the fact its the joker/batman made it feel more of a comic book thing for the UK rating board (Watchmen was 18 though)

Then again Alien Covenant is one of the goriest/disturbing movies I've ever seen and that got a 15 too lol (same with Alien Romulus)

And some previous 18 rated movies have been rerated 15 by BBFC for our current times (The Terminator, Predator, Total Recall, Alien etc)
