We've seen unfiltered jack. Generally, on camera he'll stop and glare, but I'm willing to bet junior got hit in the head a lot as a child, and sometimes he looked like he was going to walk over and belt Tammy, but if he did he obviously didn't upload the video.
I've got more family that act like Jack than I'd like, and several of them are quiet rage monsters, where they just stew in their own shittiness, glaring.
His pettiness never fails to shine through. If you like brown mustard? No. Jack will use yellow. Even if it's your recipe.
Like green enchiladas? Too bad, Jack is using red.
People get tired of the Scalfani's fairly quickly, Briana has that weird church raised look to her, she never had a chance to escape.
Even the job Jack was proudest of fired him because he has terminal DFL.
I'd go so far as to say Jack is Evil. He's a strain on an overburdened medical system, and he keeps defying god's will that he FUCKING DIE.
Re - Argyle review: Jack no like twists, they make him feel unsafe! Funny enough, most reviewers agree with his opinion here, the movie is a piece of shit dressed up like a mystery.
