Before watching the movie:
This hinges around a digital heist, but the summaries focus on the persuasion required to get the hacker to hack. Even Hollywood hacking can’t sustain a whole film (even The Net is mostly real-world action), so I expect very little of the excitement actually comes from a guy sitting at a laptop typing until the money is stolen.
I have the impression of the mastermind of the heist as a figure not directly involved in the plot aside from hiring people, coercing people, and hiring people to coerce, but there’s one more headliner than I would expect in that notion, so maybe he’s in the middle of it all, giving orders. I know far too little of use for comment beforehand.
