Hey it's a Rob Reiner movie, what could possibly go wrong? Not too much, but he's coasting here, and even indulging himself with a minor role. It's not terrible but it is derivative, with Keaton doing her adorable kooky self and Douglas his mean mother routine, concealing a heart of gold. Echoes of Bill Murray in St Vincent with his child-phobia or Nicholson in As Good As it Gets with his misogyny, they inevitably get together and it all ends in a pretty saccharine love-in. Lots of ethnic minority casting and an adorable kid, you'll either surrender to its charms or reach for the sick bag.
