I loved joker 1 and hated joker 2. For me there is only one joker film.
I felt joker 2 didnt tell any story and that was my main issue with it. The acting was good but hollow.
Also the singing every 5-10 minutes really pissed me off. Had i knew this is going to be a dumb musical i would have stayed home.
To resume, if you're going to watch the movie expecting to see the arc of main character becoming joker, you'll be disappointed.
If you looking for a musical of a sort sick love story with the joker background, go ahead.
