“No one understands the cloud!” At least not the two main characters in the new farce comedy Sex Tape. The movie recounts the tale of a long-married couple, Annie and Jay, who want to rejuvenate their sex lives. Their solution? Make a sex tape. Actually, it’s really a digital video on their iPad. The night goes as planned, but then the video somehow ends up in the cloud and soon it’s shared with the couple’s friends, family and acquaintances.
