ending ???????? I just wasted a hour and a half

This movie is a victim of sloppy and illogical writing which then asks US to write our own ending. Based on WHAT?
One should not accept this poorly written plot to begin with.
A young woman who previously seemed reasonably healthy, dies rather abruptly and mysteriously. The father suspects foul play or malpractice.
In any case an autopsy would be performed to find out what was going on. A proper autopsy would likely reveal traces of drugs in her system which were no prescribed and could contribute to her illness and subsequent death. The drugs she was supposed to be taking would be absent. Such findings should lead to an investigation.
The drug storage area is locked and accessed by a "card". Logically there should be a log of who access the room and when. I would think that some security measures would be in place. Drug theft IS a problem in medical facilities.

NONE of this is taken into account in the story line but WE are supposed to write a conclusion based on what we see and take at face value.
This has NOTHING to do with having to be "spoon fed". What we ARE being fed is pretty much a load of B.S. I dont buy it and wont eat it; spoon or no spoon.
