Well IT is only a 2 parter, and LOTR finished. The even stretched out The Hobbit films.Doubt Kong/Zilla will be taking in Avengers or Star Wars.
There biggest property right now is Fantastic Beasts. And even that was wayyy less profitable than Thor and GOTG this year.
Wonder Woman is the biggest film franchise atm. But she’s not dependant on the rest of the DCEU at all. Nor are the other DCEU movies benefiting by having her WW Star in them AHEM... Justice League!
How much profit did FB make? According to Deadline, FB was #9 in the most valuable films of that year, while Suicide Squad was #10. However, SS would have done better, if it was released in China.
