I thought it was solid. Gripping and suspenseful at the start to pique interest and twist and turns enough to hold it.
All the characters were given totally unique and relatable personality flaws and played them brilliantly.
Nicole Kidman was way too annoying for me. Perhaps it was the phony Russian accent or the fact her face was stuck in a "deer in the headlights" look with no other expression from all the plastic surgery, but I just needed that character played by someone else.
Kudos to the rest of the cast for carrying the story, but especially Melissa McCarthy, Bobby Cannavale, Luke Evans and Michael Shannon!
