TWWW - it's not complicated
***POSSIBLE SPOILER***
Okay, let's not make TWWW into more than it was. Think about it. A young Robert Redford ... Robert Redford in uniform ... Robert Redford crashing at your NY apartment (you've got him all to yourself!) ... tooling down Sunset Blvd in a sporty MG with Robert Redford ... living in a Malibu beach house with Robert Redford, a nice view of the ocean too ... taking long strolls along the shore with Robert Redford. Yes, eventually you'll have to give him up. But even then, years later, Robert Redford will rush across 5th Avenue in Manhattan to give you a big hug and tell you how great you still look.
So in other words, TWWW was, in the 1970s, every woman's sex fantasy. What's not to like?
