PARASITE open thread!

Just finished Parasite last week and found it an enjoyable read. But there were a few weak spots.
The way Sal speaks. I know she's learned English from scratch, but its weird. Not sure if its a plus or a minus.
The big reveal about Sal - saw it coming as soon as Adam and Tansy were brought into the frame.
Sal's dad. OK, he wouldn't be sweeping the house for bugs. His security team would be. And they'd also be evacuating the family to a secure facility as soon as the shit started hitting.
Also, he treated Sal like she was a willing enemy agent. Please. Again, if push came to shove, polite persuasive long term interrogations, possibly backed up with fMRI would yield amazing results. Plus that his daughter is a worm in a human suit.
Symbogen vs. US government. Really? Really? If push came to shove, I doubt that SG could stand against the FBI, or if the feds got pissed enough, the Marine expeditionary force. To borrow from Stalin, how many armored divisions does Symbogen have?
Banks. If he's a brilliant paranoid, he's incompetent at it. And so is his head of security. Two (possibly more) rival organizations infiltrated his company at very high levels within striking distance of him. At this point, he needs to throw himself on the mercy of the feds. Why? Because a lot more countries than the US are going to be looking for his scalp as the news creeps out. And I suspect they will be a lot less nice.
Dr. Cale. OK, who is backing her? All that lab equipment, counterespionage, fake identities, coma cases and similar gear does not come cheap. Who pays for it all? A benevolent billionaire (complete with volcano lair)? The mafia? The Feds?
