Director Judd Apatow gets the Zeitgeist just right in the low-key but truly funny comedy This Is 40. This Is 40 is billed as a "sort-of sequel" to Knocked Up and Paul Rudd and Leslie Mann star in both as a happily married couple. In This Is 40, both Pete (Rudd) and Debbie (Mann) turn 40, which sets off a small but irreversible midlife crisis for both. Luckily, the two have a pretty privileged and happy life. It's as though they don't even truly know how to have a midlife crisis, yet it's somehow expected. There are a lot of genuine laughs in This Is 40, many bordering on bad taste--but still hilarious. Pete's struggle with hemorrhoids is one of those movie jokes you know you shouldn't laugh at, but you do. The answer to the question "Will Pete and Debbie and their family still be cool as they get older?" is probably never at issue, but watching the two actors, who have tremendous chemistry, bounce off each other during their birthday week really is funny. Adding to the merriment is the stellar supporting cast, including Megan Fox, Graham Parker (yes, the rocker), Lena Dunham (Girls), Melissa McCarthy, Chris O'Dowd, and Albert Brooks, who truly elevate This Is 40 to a genius ensemble experience.
