A tougher question is whether you can (or should) draw any specific conclusions about those tastes or any individual representative of those groups. But just in the aggregate? Of course.
I'm always fighting against generalizations, and the subject line doesn't have enough characters for your better worded paragraph above, but part of it was to get the opinions of those in here, particular women since Miss Vicky rightly pointed out that these sites (and message boards, and movies - directors) are dominated by males. I'm always looking for the exceptions to the rule. I think it's too simple-minded to say that men prefer violence and capers while women like romantic comedies. But I'd also love to read what other women (or men) think of their fellow women's tastes, and maybe why this is so. Yeah, men are more violent, more prone to engage in bank robberies, but then you have many who say they watch movies for escapism.
Another sub-question I'd like to ask is if people can tell who directed a movie (male or female) after they've seen a particular movie. Personally, I always catch the name of the director, so its not possible unless I avoid that too, and I wonder how viewers (again, the disparity between men and women) watch a movie if they know it's directed by a woman. Do they put on a different lens trying to understand the female point of view, and the female characters? I'd love to do an experiment where I show movies, but intentionally flip the genders. I think some would say "Yeah, see, typical woman" despite it not being typical. I'd like to quantify what I think I know; that we are prejudiced, but to what extent, how much, and can we fool ourselves or be fooled? I'd love to see adapted movies made by each gender and see if there is a difference or at least an emphasis. From my observations, it seems men are moving into the direction of women, and vice-versa. To throw another curveball, I wonder how much of this is organic and how much is conformity because of social norms. I think the latter, but I also acknowledge that certain traits are not as necessary.. Men don't have to be as strong because we aren't killing our food by hand or having to live in the wilderness surrounded by unforgiving nature. I don't know if coming closer to the center is helping, I'm starting to think we might need complementary relationships for balance. I wouldn't want young women to ever feel that their decision to be a "stay-at home" mom is weird. My only wish is for people to be their true selves as much as possible, which is why I post this stuff and then paste it onto twenty other message boards (more comparison, more results, stratification).
