With The 40 Year Old Virgin, Judd Apatow tracked the story of a man anxious about missing one important signifier of adulthood, and he returns to that same fertile territory in his new film This Is 40, where Paul Rudd and Leslie Mann are about to turn the big four-oh and are freaking out about it. Should they start exercising more? Should they have a better relationship with their kids? Can any perspective be added by a supporting cast of Apatow all-stars including Melissa McCarthy and Jason Segel? It all seems perfectly pleasant, and it ends with Rudd throwing his legs in the air to investigate his taint with a mirror, so can we assume you're in?
