“Equity” (**1/2 out of four) was a diverting but derivative melodrama set in NYC about a Wall Street senior investment banker (Anna Gunn) whose affluent life gradually is becoming undone by a financial scandal and corruption and is being investigated by her former friend (Sarah Megan Thomas) who is now a federal prosecutor. Adrenalized story of wheeling-and-dealing among the rich and powerful holds your attention with its good performances and storytelling but is never enthralling or engrossing as it could have been, because we’ve seen much of this story before in “Wall Street”, “Boiling Point”, and “Margin Call” among many others. A good attempt by Meera Menon which may have been more timely and original 10 years ago.
