I don't recall if I saw Prospero's Books with you (after you'd seen it this time) or just on your recommendation, but it was, um, bad. Expensively bad.

As mentioned in another thread, I thought that Excalibur looked like a good first date movie, but when you're 17, that early owie-sex scene was far too ... well, far too much.

And when one has attained more maturity, there are other good date movies. Such as Plan Nine from Outer Space.
