I think it's a really clever, entertaining, fun film, and f a r better than IMDB's measly 6.3.
As a Steven Soderbergh production (that could have just as easily been a Coen Bros. production), it has that whip-smart, surreal, quirky vibe, but, it is based on actual events (see The Panama Papers, Mossack Fonseca, or Jürgen Mossack), which elevates its many eccentricities and absurdities to a higher, almost unbelievable level. Real life often is stranger than fiction, and that's certainly the case here.
I couldn't help thinking that it felt like Raising Arizona, The Big Short, Logan Lucky, and Vice thrown in a blender. You know, Adam McKay and Moneyball's Michael Lewis sorta stuff.
In actuality, the screenplay was written by Scott Burns, who also wrote Contagion, The Bourne Ultimatum, and 2019's The Report, and produced Al Gore's An Inconvenient Truth (parts I and II), so it has that tick-tock-conspiratorial-world's-on-fire ethos, which I love.
