I'll try to keep this short and simple.

Rating: 9/10 (28 November 2019)

I actually hated how much I enjoyed this movie, DC so far haven't made a single good solid movie in their many many attempts, at least in my opinion, Wonder Woman, which is for some reason seen as a good film... I hated it, thought it belonged in that era of early 2000's superhero films that weren't good, weren't bad, but were finding their footing and setting the path up for things to come, a learning curve if you will.
Anyway, I was so blown away by how amazing this movie is that I was actually kind of annoyed that I finally had to admit DC had done something truly amazing, from acting, writing, cinematography... just everything, was brilliant.
The biggest question that I seem to be consistently asked is who was better, Joaquin Phoenix, or Heath Ledger, and I think I have the best answer for you.
Neither, they are incomparable, If you were to have them each play the other joker in the other film, the results would be completely different, Ledger was an amazing villain for batman, Phoenix on the other hand would not be an amazing villain for batman, but that doesn't make him any less of a joker, they are both absolutely amazing in their own rights, they have each managed to capture a character in two completely different lights and make something amazing.
