Alright, well if you want to buy me a TV and a TV licence I am more than happy to watch all the weekend telly and make you a lovely list? How does that sound?
Or how about I say "There are many female gorgeous TV presenters in their 20s, there are no male ones that I can think of". Suit you? I can't name dozens of anything, really - cheeses, dog breeds, James Bond films - it's hyperbole dahling. But there are a lot, I've named some, don't be a moaning minnie and throw my benevolence back in my face.
Of course I can refute that point, about the president. Few films consist entirely of conversations on one subject alone, or where "the president" features in every line of dialogue. That would be both boring and ridiculous. There are what-I-call subplots for a start, and conversations establishing background. Films aren't the same as news articles.
Anyway, if all you can say about the Bechdel test is "it's not perfect" then it strikes me that you are wilfully gliding over it's main point, which is that there are vanishingly few female characters in the first place, even fewer who talk to each other. Why not have some fun this weekend and apply it to your favourite movies?
