I'm answering to the part about "The Pacific" and "Band of Brothers" only because I'm fresh of the first two episodes of "The Pacific". They arrived in Italy for the first time only yesterday evening. So, I know I should wait for the serie to be completed before speaking :) but for what I've seen 'til now, I prefer "Band Of Brothers" a lot. I think the production increased the quality of the part regarding battles and history (though admittedly I understood a lot of citations only because I'm already a huge WWII reader), but the character deepness and personal histories and dramas in BoB are by far better carried out. I'm waiting for the other episodes, hoping to be denied.
