Yeah, I know “Office Christmas Party” (2016) is stupid, but it’s appropriately stupid for the plot (epic gesture needed to save the company). It’s necessarily stupid for its genre (R-rated farce). Simply put, it’s just the right amount of stupid (although I saw the unrated version, so, technically, what I saw was extra stupid). Jennifer Aniston and Jason Bateman have made like 377 films in the past few years, so they seem to be homing in on a formula in which they’re both uptight and everyone else is crazy (although I do wish the formula involved my seeing fewer penises).
