Xerxes - Frank Miller back again with a 300 sequel... or prequel?

Here you have it, Frank Miller back on the horse (pun absolutely intended) with 300's sequel (or prequel?). I'm still not sure where in the Battle of Thermopylae this next story will take place, but guessing by the scar on Xerxes face, I'm guessing it will be take place after the events of 300. Surfing the internets, it seems like talking badly about Frank Miller is the "cool thing" to do these days. Is it because Frank Miller's adaptation of The Spirit left a bad taste in everyone's mouth? Maybe. Even I didn't care for his vision of The Spirit that much. However, I'll continue to ignore the naysayers and see support what Frank's got up his sleeve.
