In short, it's a PG plot for an X-rated story.
A tired premise and a sheen of desperate flop sweat tanks this DOA comedy, which plays more like an ancient Playboy doodle than a full-fledged movie.
Even for a farce, the situations stretch credulity far beyond the breaking point.
It's strange to watch a comedy full of talented people that does not work from the opening scene. It's like eating food and not tasting anything.
Sex Tape is 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 innate likability of stars Cameron Diaz and Jason Segel.
At heart, it's about as naughty as an old Disney movie with Dean Jones, Suzanne Pleshette, and an unruly Great Dane. I liked its gung-ho slapstick spirit, though. No one's slacking off.
Sex is treated first as brainless imperative, then as acrobatic duty, then as desperate consequence - it's never sexy in any way.
The folks behind Sex Tape did their homework. They just forgot the laughs.
Yes, there are some laughs, but they're not as big or as frequent as one might expect from a would-be "major" comedy.
