Of course, it probably helps that my familiarity with the actual Illiad is on about the Big Golden Book level.
But you see, now the movie won't be spoiled by the original *snort*.
Actually, as I was saying to my companion, if all the movie does is make a few folks go out and read/research the actual story, it's a success in my book.
One aspect of the "that's not how it happened in the book!" arguments in this case in particular is knowing that "how it happened in the book" probably differs a fair bit from any factual historical events as well. But we do love our little ink-scratches on paper, with a fierceness that gives them a reality all out of proportion with any requisite accuracy.
Stories are slippery and flexible, and that's one of the best things about them... to me. Mythic stories yet moreso.
