After the ending
I just saw this again on one of the channels on the ROKU.
I know we're supposed to suspend all disbelief but if they continued on in the movie after coffee shop guy and Susan walk away, what would have happened?
"Where's Dad?" Susan would either have to explain or keep her mouth shut and let someone else discover the body.
Coffee shop guy would say that Susan already knew he was dead before the body was discovered by her statement that she wishes he could have known her father.
Sister would ask Susan how she knew their father was dead and why would she leave him lying there on the other side of the hill to go back to the party.
Somehow, Coffee shop guy would have to explain how it wasn't he didn't murder their father and he doesn't know what happened to himself either. Susan would have to explain this supernatural occurrence and I don't know how that would stand up in a court of law if it went that far.
Susan might have to admit to Coffee shop guy later how she had sex with his body and why was she attracted to what she later discovered was "Death". Does she love Death more than he?
I just can't imagine the fiasco after the ending even within this movie.
My big question in the beginning would be how such a smart man who is either having a mild heart attack or angina wouldn't have gotten his butt to a cardiologist asap and gotten checked out. Yes, he could have still died when his time was up but you'd think he'd go to a doctor despite hearing voices.
