Manhattan endures because Manhattan endures. You can go to the city today, this afternoon and live your life amidst the romance. It is there and calling to you if you want it. Gershwin remains if you listen.
It’s so obviously one of the perfect romantic comedies that other all-timers reference it directly (The run at the end of When Harry Met Sally is basically shot for shot).
The performances are perfect. Diane and Meryl - the two greatest screen actresses of their generation, are perfect.
Is it even possible to make a comedy this good anymore? Was it then?
