yeah Jarhead was a total let-down in my eyes too but this Flags of Our Fathers by far surpassed the let-down level compared to Jarhead.
It had so much potential to probably be one of my all-time favorites war movies if it would have stayed to the war scenes and futher more displayed what was going on during the invasion and possible the complete securing of the island from the entire Japenese force. I mean theres alot of famous battles that happened there because the island was so strategic to both forces.
