Should be called PlotHole Nocturne
Seriously, I have never seen so many plot holes trying to insult my intelligence.
Billionaire not using professionals to figure out where the mail is coming from (would take a day to figure this out)
Rich widow using a reporter to find out who killed her husband, while she is the killer? Oh, but that's not she wanted, is it? She wanted him to find the materials as well, except she didn't tell him that. Ooops...
Billionaire's henchmen beating up, shooting kid, of an already well-motivated reporter. What, why??
And at last, the icing. Billionaire gives the reporter a key. The Key. The one he needs to progress in the story and draw it to conclusion. Except billionaire doesn't even know that this key is important to our poor reporter. So why does he give it to him? WHY???
