Braveheart wasn't all that accurate, either (from what I've heard) and the Henry V speech was lifted in a weird way. HOWEVER -- it was a good movie. It was exciting, action-packed and had a few laughs. That's all I want from a movie. I want to buy my ticket, get the popcorn, soda and twizzlers, and get a little excitment and a couple of laughs. If I want accurate history, I'll read a book.
That's my point, from what I hear, "Alexander" is no "Braveheart"...MUD
