I found that I felt the length with this one, where I didn't with the first.
Also I feel like it wasn't a Joker movie at all, but like mentioned, a psychological drama exploration of mental illness of this man Arthur Fleck. And with it supposed to be a Joker movie, many parts of it annoyed the hell out of me - I kept saying, "that's not the Joker!!"
Turns out I was right, supposedly the director wanted to make the first movie but it didn't get accepted until they tweaked it to add the Joker IP into the character
Taking away that lens, I enjoyed it significantly more
Not OP, but Digimon Abridged, cos I just love abridged shows lol
But seriously, Adventure 01, the original show was so awesome. My first ever experience with an Isekai developed my love for them!
