Now, by limiting yourself to shows/movies that pass the test, you'd be cutting out a lot of otherwise-worthy entertainment; indeed, a fair number of top-notch works have legitimate reasons for including no women (e.g. ones set in a men's prison or on a WWII military submarine or back when only men served on juries), or with no conversations at all, or having only one or two characters. You may even be cutting out a lot of works that have feminist themes (it's been revealed that Mulan surprisingly failed, although it does make a twisted sort of sense ? she spends the majority of the movie as the sole woman in a male-only group of soldiers, with the rest of the time being around women who are fixated on her wedding, which she was obviously uncomfortable with). But that's the point; the majority of fiction created today, for whatever reason, seems to think women aren't worth portraying except in relation to men. Things have changed since the test was first formulated (the strip in which it was originally suggested was written in 1985), but Hollywood still needs to be prodded to put in someone other than The Chick.
The test is often misunderstood. The requirements are just what they say they are ? it doesn't make any difference if, for instance, the male characters the women talk about are their fathers, sons, brothers, platonic friends, mortal enemies, patients they're trying to save or murderers they're trying to catch, rather than romantic partners. Conversely, if a work seems to pass, it doesn't matter if male characters are present when the female characters talk, nor does it matter if the women only talk about stereotypically girly topics like shoe shopping ? or even relationships, as long as it is not relationships with men.
This is because the Bechdel Test is not meant to give a scorecard of a work's overall level of feminism. It is entirely possible for a film to pass without having overt feminist themes ? in fact, the original example of a movie that passes is Alien, which, while it has feminist subtexts, is mostly just a sci-fi/action/horror flick. A movie can easily pass the Bechdel Test and still be incredibly misogynistic. Conversely, it's also possible for a story to fail the test and still be strongly feminist in other ways, and there's nothing necessarily wrong with that. What's a problem is that it becomes a pattern ? when so many movies fail the test, while very few show male characters whose lives seem to revolve around women, that says uncomfortable things about the way Hollywood handles gender. There are also lesser-known variations of the rule, such as the Race Bechdel Test, in which two characters of colour talk about anything other than the white leads and the Reverse Bechdel Test, with the roles of men and women swapped.
