Hi Les,
I'd watch 2001.
For a start, it is arguably the only movie worthy to be permanently on show
alongside the great masters in the Louvre.
But great art is not valued by everyone and some will find it impenetrable.
That way you can accidentally watch The Right Stuff again when your
partner is there. It is more accessible and you can simply mutter that
it is in the popular main-stream action hero genre.
