Sex Tape is such a dumb movie that it's hard to know where to start. So let's try this: Its premise is total nonsense. Married-with-kids couple Jay (Jason Segel) and Annie (Cameron Diaz) decide to spice up their inert love life by filming themselves with Jay's iPad doing every position mentioned in The Joy of Sex. But after their naughty three-hour film finds its way into the Cloud, all their friends and family have access to it thanks to the iPads Jay has given away as gifts.
GQ has checked with Apple to confirm that such a thing could never happen, and sure, dopey comedies have silly setups all the time. The real problem is that Sex Tape doesn't make sense in any regard. It's yet another "shocking" R-rated comedy that's so toothless and witless that the nudity and swearing are actively irritating, reminding you of the idiocy surrounding the dirty parts.
Segel and Diaz have reunited here with director Jake Kasdan, who all worked together on Bad Teacher, which was itself a Bad Santa ripoff set in middle school. Once again, Diaz is incredibly game, flaunting her sex appeal and fearlessly flashing lots of skin in the name of raunchy comedy, while Segel plays the hundredth iteration of the bozo husband who can't believe he landed such a beautiful wife. Sex Tape's conceit is that when Jay and Annie first met, their connection was primarily sexual: Love eventually followed, but 10 years into their relationship, they still take great pride in how much screwing they do. Well, how much screwing they used to do—now, as in every bland Hollywood comedy, they're clichéd boring parents who can't find time between kids and jobs to schtup. (Wealthy, self-absorbed, and living in Los Angeles, they're a slightly more tolerable version of the couple in This Is 40.)
