The surreal and silly sequel to the hit 2015 comedy skates on the well-known but still-appealing comic personas of stars Will Ferrell and Mark Wahlberg and their zany chemistry.

Like the passable original, this formulaic comedy can’t stop teasing the possibility of a funnier, smarter movie being made with the exact premise, central conflicts, and stars.

It arrives at a moment when the crackling voltage of the culture wars — blue state vs. red state, Trump haters vs. Trump lovers — is coursing through every fiber of the nation. This means that a film like Daddy’s Home 2, in its stupido-on-purpose way, can seem almost relevant in its trivial hit-or-miss yocks.

Daddy’s Home 2 wants points for exploring the ever-expanding family tree in a Christmas comedy, but it only barely succeeds. Lithgow’s delightful grandpa offers a welcome diversion from the madness, but those moments are as fleeting as the plate of cookies left out for Santa on Christmas Eve.

It’s hard to know if this clunky comedy is part of Mel Gibson’s redemption arc or some strange new form of karmic retribution.
