Except that has absolutely jack-shit to do with whether the movie was made by DC and whether it was a success or not. The general audience doesn't care if it's Joker in name only, they care if they enjoyed the movie or not. The verdict on that seems clear - they enjoyed the movie.
Yep.
The foreign box office performance of this movie has been extraordinary. Wonder how much of the world really even knows or cares that it's connected to Teh Batman? Meh, fanboi stuff.
