My friend has a strange claim about 300

[DuFresne]

He says that the argument is based mostly on how the movie tends to focus on the glory and honor of being in war and staying there til the very end. He also says that graphic novel does not put as much stock in this, as Leonidas faces opposition to this radical view more readily in the graphic novel. Again, I can't say if any of this is true as I have not seen the movie nor read the graphic novel.
