Sex Tape might be the funniest movie about sex under the corrupting influence of marriage since Eyes Wide Shut. It's warmer and more amusing than its ads would lead one to believe. In fact, it's almost good enough, leaning a little too hard on the likability of Cameron Diaz and Jason Segel. They play Annie and Jay, a couple of married-with-children Angelenos whose libidos seem to have Logan's Run their course.
Oh, is that reference to an ancient sci-fi set in a world where this sort of trouble doesn't come up much because everyone gets euthanized at age 30 obsolete? So is the premise of Sex Tape. The film wants us to accept that Jay -- a gadget guy who has some undefined job in the music industry that's earned him so many extra iPads that he hands them out as gifts, not just to close relations but to the mailman, too, like he's Oprah Winfrey of Nazareth herself -- doesn't grok how the Internet works.
Jay's amiable, sitcom-dad cluelessness might go down easier if Segel weren't one of the film's three credited writers. When Annie and Jay can't get it together during a night away from their two adorable moppets, they resort to making an iPad sex video. But when it threatens to go WikiLeaks, thanks to all those hand-me-down iPads, Annie's fat blog paydays -- and her and Jay's dignity -- are endangered.
And so for a very long time, Sex Tape ceases to be a sex comedy, and turns instead into a kinda-sorta-not-bad chase flick wherein Annie and Jay attempt to recover all their iPads, presumably so they can use a Sharpie to redact the naughty bits.
