I too absolutely loved Band of Brothers, and would rank it somewhere probably in my top ten or twenty series of all time. I've been really anticipating The Pacific ever since I read of it going into production in Variety, because we all know with Speilberg on board it's going to contain some simply epic battle scenes. That said, when I was watching the trailer, I couldn't help but kind of laugh halfway through because I'm not a big fan celebrating war as this glorious thing and treating it like an action movie. I prefer a more realistic approach, like Black Hawk Down or Platoon, or maybe even Hamburger Hill.
Still, I'm looking forward to this. It will certainly contain some excellent set pieces and battles, so you really can't go wrong here.
