I don't know about the joker tho, I feel like it's separation from comic book material and creating a new unknown version of the joker won't have large appeal from GA
I read the script and I think that the movie is great as a psychological thriller, but not CM movie about one of the most known villans of all time
Idk, maybe I change my mind when I see the movie, but have bad feelings about it now.
Jumanji looks great from the trailer, it will drop a bit domestically but can make a good amount WW.
IT 2 also can perform well and top the first one WW, specially with the lack of competition( the first was good but not great TBH).
Doctor who looks good too and should perform well.
So yes, second have of 2019 looks a bit promising for other non- Disney studios, specially WB
