It's just like that scene in 'The Matrix' where Keanu Reeves is in that robo-bathtub... except its not entertaining nor does it make sense. In fact, it *is* just like 'The Matrix'!
If I'm right about this, it's porn for people who get off on watching women struggle helplessly, trying to escape from whatever predicament they're in. There are enough of these fine folks to necessitate an entire line of movies involving nothing but women tied up, strapped down, or suspended in improbable and likely uncomfortable positions, generally with the Hitachi Magic Wand strapped to their nethers in an effort to force them to orgasm as they writhe, ostensibly attempting to escape.
