If you ever care to make that email public I'd love to read it.
It's really not much more than what I posted, but here it is:
Hi Jonah:
I've seen GD many times, and also think it's one of the greatest movies ever.
To me, the essential meaning is that until someone loves and cares about someone else, not in a narcissistic way, but in a deep and abiding manner, life is meaningless and every day is fundamentally empty and the same.
Oh, and it's very funny. One of my favorite moments is when Murray drives the pickup into the quarry pit.
When the truck crashes, cameraman Chris Elliott, who of course detests Murray, half-heartedly says to Andie McDowell "he may have survived." Then the truck explodes in a tremendous ball of flame, whereupon Elliott laconically observes "well, maybe not."
Regards,
