Heh, heh. I haven’t formulated it on movies either. In my case also, it is on personal relationships. I offer the movie as comic relief.
Oh, and I’ll have what she’s having...
Both movies are pretty funny in their own way.
And maybe the main problem is that I am looking at this from the male perspective while you are looking at it from the female.
The whole running “gag” in When Harry Met Sally, which is actually BASED on what I believe to be the truth, is that men cannot be friends with women. There is always the sex drive.
I'm inclined to doubt it since I'm not in any way female. I do however have a great many female friends. despite being married for the last 17 years. And yes, a couple of those friendships were hotter relationships at points in the past.
