This makes me fear as a result of this was presupposed to be a trilogy for some time(I forgot once they stated it) so how are you going to have a ending that hurts the subsequent film? Like when this was being filmed and doubtless written they knew it was getting a sequel so HOW?
I do not perceive why corporations make trilogies or a sequence if you do not know the place it would go simply plan it out that is not troublesome. Have a starting center and finish and determine find out how to reduce it into films.
This tells me that both the writes do not care, the studio did not care, or everybody concerned did not care which is worrying since that is the way you get dangerous films.
