Undermines it's own mythology, and lore.

Rating: 8/10 (6 October 2019)

For some this is a 10/10 movie, but for me this is a 6/10 movie. I think this one suffers somewhat due to undermining it's own mythology.
No spoilers by the way, but not only is the audience (us lot) given a Joker origin story, name and all that, but the whole of Gotham is too. That might seem like a relatively minor misgiving, but actually linking this to Batman at all did the movie no favours, and it goes a little bit too far with it's Batman references too - in particular Batman's own origin story being regurgitated once again - not a spoiler really, though the event is featured.
I personally feel that this movie would have been much better if it left you feeling it could have been a potential origin story for the joker, leaving you with ideas like "Oh, I wonder if that could be Batman's Joker." It's all a lot more on the nose than it needs to be really, but worse of all removes all aspects of Joker mythology and lore from the long running narrative.
It really needs a fanedit to strip away all Batman references, so that it's it's own thing entirely. You know what, if that had occurred it would have been an easy 10/10 movie. Loved the performances in it, and it's considerably grimy feel, but other than that it just went a little off the mark in terms of giving Gotham too much information.
