Story: Zack Snyder, Kurt Johnstad, Michael Gordon (screenplay); Frank Miller, Lynn Varley (original work)
This is one of those movies that I have to qualify as the "see in theatre" type. And I have to say, I wasn't disappointed in the least by that decision. Visually, 300 is exactly the kind of movie that deserves a large screen and loud speakers (exceptionally good ones probably aren't necessary, but the loudness is). While I'm certainly no art critic, there was enough well-done cinematography in the movie that even I could notice.
For those who aren't aware, once you get back through the movie and the graphic novel, the story itself is based on the Battle of Thermopylae, between the Greeks and the Persians. While some storytelling undoubtedly went on for the sake of making an enjoyable movie, the premise remains the same: The king of the Spartans, along with 300 of his men, and (in the historical event) 700 diverse other Greeks, met and held back the invading hordes from Persia for several days.
In the end, it's the story of men who loved their country so much that they were willing to fight to the death to defend it. My first thought was actually a Heinlein quote, so I'll just end with that:
"The noblest fate that a man can endure is to place his own mortal body between his loved home and war's desolation."
