It was much better as a graphic novel. Anyone who read the series would immediately say that the red backdrops defined the mood, and it was missing here. 300 translated its source material perfectly, but was just a little too much of style over substance.
Did anyone here read "Gates of fire", a novel on Thermopylae? That ranks as one of the best novels I have read, and to be honest, should have been the source material for the 300 movie.
