“Office Christmas Party” (*1/2 out of four) was a humbug Christmas comedy about assorted office workers (Jason Bateman, T.J. Miller, Courtney Vance, Olivia Munn) throwing an epic office party that grows progressively out of hand when their bitchy new C.E.O. (Jennifer Aniston who can play this role in her sleep by now) announces she may be shutting down their branch. Film is like being stuck at a party with a bunch of loud drunks you want to leave and go home from. Needlessly dumb and contrived, with only a few laughs, and only the good-natured performances of its cast to keep it afloat.
