Joaquin Phoenix saves this from being a disaster.

Rating: 6/10 (20 April 2020)

I left the theatre thinking that Joker was a great a film. I then thought for 2 minutes about what I had just watched and came to the conclusion that I didn't enjoy the actual film, I enjoyed Phoenix's performance.
The film is fine as a stand-alone character study drawing inspiration from films like Taxi Driver and King Of Comedy, but compared to these films, it falls flat on its face.
The only things that were unbearable in this film for me was when it tried to include itself in the larger DC universe and the complete lack of subtlety at times where the film assumes that the audience are too stupid to infer something shown without it having been spelt out for us, so for an R-rated movie, that felt insulting.
Every other aspect of the film was tolerable.
I don't think the film was great but fans of DC will probably like it.
So, if you're a DC or Joker fan, you'll probably enjoy the film, but as somebody who isn't invested in DC I found this passable but laughably bad at times.
