Oh there are whole websites dedicated to assigning pass / fail to every movie based on the bechdel test. I just can't remember a part of titanic where two or more women are talking to each other.
I think it is worth something. It is deff a flawed metric but how many movies pass/fail for a given set of time changes over the years is still interesting if nothing else. (I think how widely known it is screen writer might just add an extra scene at this point to make sure they pass)
