I'll make this one short and sweet, quoting Jimmie Walker by saying that Miss Sloane is "dy-no-mite!"
It's awesome.
Do NOT let IMDB's debbie downer 5.9 throw you.
It's got the pacing and dialogue of David Mamet's or Aaron Sorkin's work, even featuring The Newsroom's Alison Pill, but without all the annoying pretentiousness. And best of all, it packs an unconventional wallop that you've gotta see to believe. You'll hate it, then you'll love it, then you'll kick yourself for not loving it sooner. It's brilliant, intellectually viced, and comes at you like a rat-a-tat-tat-tat psychological thriller from 'second zero.'
And gosh, have I missed Sam Waterston.
Plus, how can you go wrong with Lithgow, Chastain, Mark Strong, and Gugu Mbatha-Raw (who is on an absolute tear, having now starred in Concussion, Free State of Jones, Jupiter Ascending, Beauty and the Beast, a new Cloverfield installment, Belle, and Larry Crowne)?
Hasten forward quickly there!
