Are you lacking for it these days?
I watched 300 in my cinema seminar class today, and it did not hold up well to the standard I set for it when I was 17. Hell, the last 15 minutes or so were flat out boring.
I also don't know exactly what we were watching for. We were supposed to be watching the special effects and how the actors interacted with the simulated space, but I'm not exactly sure why I was looking at that from a posthumanist standpoint. I'm anxiously awaiting having it explained to me this Friday.
Edit (mostly for Barbosa's sake): And I just learned that Xerxes was also known as King Aẖashverosh, the king of the Purim story! For all you gentiles out there, the Purim story is basically about how a Jewish queen saved her cousin Mordecai and the Jewish people from an anti-Semite named Haman (pronounced Heyman, go figure) by revealing to her husband, King Aẖashverosh, that she was indeed Jewish. Aẖashverosh decided to execute Haman instead and made Mordecai his chief adviser.
Basically it's a story about religious tolerance and nepotism.
