Greg McLean directs John Gallagher Jr., Tony Goldwyn and John C McGinley in this efficient Battle Royale in an office block thriller. 

Neat and gory. A simple, unpretentious murder fest. It lacks that invention or that escalation such an endeavour really needs for me to wholeheartedly recommend it to those not into their schlock… but for The Belko Experiment’s  short, nasty runtime I personally was gripped. Lots of likeable C-listers fill the lobby too which never hurts such an outing.
