I suppose I need to start my review of This Is Where I Leave You by coming clean and saying that I read Jonathan Tropper’s novel on which his screenplay is based and hated it. Filled with endless turns of cliché situations and characters that seemed discarded from NBC’s 2004 pilot season, the book never made a case for its popularity in my mind. Still, based on the cast director Shawn Levy (The Internship) assembled I hoped the film adaptation would be able to smooth out some of the book’s trite developments and be that rare unicorn where the movie was better than the book.

Alas, while the film does ultimately fare better than its source material, it remains a painfully laborious affair with no family squabble left un-squawked and no amount of gooey angst left un-squeezed. While Tropper has streamlined his novel for the big screen, he wound up throwing out more than a few interesting elements that provided these characters with what little interest they were sketched with in the first place. Particularly disappointing is the full-scale lobotomy performed on eldest brother Corey Stoll’s (Non-Stop) backstory, robbing the actor and the audience of some meaty insight into why the man is so gruff and glowering.

Returning home to sit shiva (a Jewish mourning period of 7 days where the family receives guests and remembers the deceased) the Altman children come back to the family homestead with baggage both physical and emotional. Cuckolded brother Judd (Jason Bateman, Bad Words) is dealing with his marital woes, unhappy sister Wendy (Tina Fey, Muppets Most Wanted) juggles scampering children and a non-present husband, responsible brother Paul (Stoll) can’t seem to get his wife (Kathryn Hahn, We’re the Millers) pregnant, and free spirit Phillip (Adam Driver, What If) speeds into town with his older fiancé (Connie Britton, The To Do List) in tow.

Living under the same roof again with their famous child psychiatrist mother (Jane Fonda, Peace, Love, & Misunderstanding) could have made for a much more interesting mix of comedy tinged with pathos but Tropper and Levy hardly let a moment go by without a joke involving Fonda’s silicon-ized breasts, even sacrificing a hugely emotional scene near the end of the film to get in one more boob joke.

It’s time for Bateman to hang up this exasperated character he’s been playing for several decades now. He’s interesting enough of an actor to take some stretch opportunities but he’s returned to this well one too many times. Though he creates some nice sparks with Rose Byrne (Insidious) as his high school sweetheart, the rest of his performance seems flat and workmanlike. Hahn is mysteriously underused here, like Stoll she suffers from Tropper’s slicing up of her story arc…though it must be said I’m glad he removed one particular turn of events that would have had audiences furious. Britton barely makes an impact and while Fonda gets some of the best scenes in the movie, she looks like she’s going through the five stages of Botox as the film progresses.

Driver may be the next big thing but I’m yet to be sold on his charm – still, in his own way he gives the role some needed charisma, however oddly he delivers it. Though it pains me to say it, Fey is the real mistake of the film. She probably should have swapped roles with Hahn because her attempts to dig deep find her in shallow waters that she just isn’t yet capable of navigating.

It doesn’t help that these characters are the kind of gross oversized family unit that only can be displayed on the big screen. My movie companion thought that I missed the point because, as an only child, I may not be as in tune with the family dynamics that exist within a large household. This could be true but my problems lie not with the device but with the execution. Worse, the film introduces these messy people and then dares to provide the tidiest of wrap-ups without earning it. Instead of feeling sympathy for the misery everyone is enduring (of which none is related to the death of the patriarch, by the way) I felt like everyone got what was coming to them in one way or another.
