I could really care less about what stereotypes it uses or doesn't. Funny is funny.
Well, if you're a guy, your life doesn't require that you care, unless you identify as feminist and/or are genuinely concerned about gender issues. You're not the one who gets penalized at the job interview or other work situation because people, even highly educated ones, have asinine, prejudiced, incorrect ideas about men's and women's alleged essential differences. Some of these ideas are constantly reinforced through endless repetition in mainstream media, including sitcoms.
And how anyone can argue that anything is objectively funny...wha?
Jon: I don't think I was arguing that drama/SF couldn't accommodate strong female characters, but thanks for the sitcom refs. Do consider however, the overall ratio of men to women, far fewer "character actresses" relative to character actors (older, fatter, non-leads), who is considered the star/lead of a given show, what the arc of the characters is like. If male characters are deemed "foolish," and that's the root of the show's humor, isn't that, in some sense reinforcing a sort of "boys will be boys" mentality? I'm not really sure that's so swell for women. Most of my married women friends report that their hubbies deploy that kind of feigned incompetence to attempt to get out of any number of housework/parenting activities.
As a side note, for those of you who like the Stieg Larsson trilogy, the full trailer for the American remake of "The Girl With the Dragon Tattoo" (Swedish title: "Men Who Hate Women") is out now. If you're familiar with the original film you'll note that they appear to have altered the leads' genders for the American version--Lisbeth is more feminine, Daniel Craig is butching up Blomkvist relative to Michael Nyqvist's original portrayal (which is actually what made the story work in the first place). Appears to be dumbed down in a number of ways for an American audience, but gender is a part of that equation. Arg.
