Ten years ago, a motion picture starring Tom Hanks and Julia Roberts would have been blockbuster material. Today, it plays weekend second fiddle to a mindless movie about shape-shifting robots. The irony of this film's title is that by the end of this sanitized rom-com, we actually know surprisingly little about the title character, who is a suddenly jobless average Joe who enrolls at the local community college to rebuild his résumé for the 21st century. We know that Larry (played by Hanks, who also directs) is divorced and buried under debt, but we're left clueless as to how or why this milquetoast got to this point. Instead, we watch as Larry's free-spirited classmate Talia (Gugu Mbatha-Raw) invites him to join her scooter gang, updates his wardrobe and goes feng shui on his living room. And, of course, Larry gets sweet on his public speaking teacher (Roberts), who is caught in her own unhappy marriage. The script is by Nia Vardalos, which means it's as sappy as a tapped Vermont maple. While Hanks and Roberts are as charming as ever, they lack credible romantic chemistry. As the story peters out, it leans almost exclusively on those old reliables: Hanks' aw-shucks routine and Roberts' toothy grin.
