It's pretty bad. I like musicals but that's not what I came for with a Joker 2. The songs and visuals were not that great so it all kinda fell flat. There was absolutely no moment where Joker and Harley do anything like rob a bank or something... just them breaking out into musicals and getting rowdy. Like. What? Dafuqu did I just watch?
It almost feels like it tried to suck. Like it was crapping on the reason the original movie had a cultural impact. It seems to undermine people relating to Joker's uprising against the elites and show us that being a Joker is a bad thing and will leave you getting beaten and singing musicals in an insane asylum.
