It looks visceral, exciting and about as historically accurate as "The Little Mermaid" but I guess the true legacy of Thermopylae isn't historical, it's emotional:
Then up spoke brave Horatius
The captain of the gate,
"To every man upon this Earth
Death cometh soon or late.
Then how can men die better
Than by facing fearful odds,
For the ashes of their fathers
And the temples of their Gods."
