Starring Jason Bateman and Tina Fey. Rated 14A.

There are lots of ways this dysfunctional-family comedy verges on going wrong. Like, Sex Tape­ wrong.

It opens with Jason Bateman’s Judd coming home to find his boss (Dax Shepard) nailing his wife, for example. Haven’t we seen that before? Then there’s the toddler who brings his potty into every room to poop, and Jane Fonda’s massive fake breasts getting the full Benny Hill treatment. But for every time you’re reminded that Shawn Levy directed this—he of the Night at the Museum movies, among other bag-of-hammers studio comedies—you can comfort yourself by watching this fine ensemble cast groove on each other.

Who wouldn’t want to hang out with a family played by Fonda, Bateman, Tina Fey, Adam Driver, and Corey Stoll (of House of Cards)? Plus, wives and girlfriends played by Connie Britton, Kathryn Hahn, and Rose Byrne? When Timothy Olyphant shows up as Fey’s brain-injured old flame, it’s officially an embarrassment of riches.

Their occasion for coming together is the death of dear old Dad, who at least isn’t forgotten immediately after the funeral, as is the jarring trend in these sorts of films. Dad’s last wish was for the family to sit shiva for him, so Mom (Fonda) makes the kids stay under one roof for a week. Way too much happens in this brief period, from Judd meeting the overgrown Manic Pixie Dream Girl (Byrne) who’s going to rescue him from his failed marriage, to Driver’s overgrown idiot making a mess of his own relationship.

For all the sitcommy shenanigans, though, every character gets moments of truth and dignity—especially Bateman, who serves as an excellent, melancholy anchor.

But maybe not the toddler. There’s no dignity for him.
