Michael Crichton's Coma (1978) is a good example. In many ways the movie is the first modern thriller with a female heroine (Genevieve Bujold) who has a boyfriend (Michael Douglas) who has been pretty much useless in supporting her efforts all the way through the film. She does all the work, all the investigating, all of the reasoning out, all the discovering about who the killer is (a rouge male doctor selling body parts). Sherlock Holmes couldn't have done a better job than she does. So, yeah, very positive statement about women, right? Not so fast. At the climax of the movie Bujold is knocked out on an operating table about to be killed by the evil doctor and she has to rely on her dumb-ass boyfriend, worthless to this point, to save the day and rescue her. As Dandy Don Meredith used to say "That tells you a whole little story right there itself, now, doesn't it?" None of the creative folk involved with the movie is consciously making that statement but the end result is a subtext that says in effect "Yes, women are equal, but let's not take this too far--They still need to depend upon a man to save them in the end."
