It's very good. Not as good as BoB. I think that lull in the middle is where most people started to get bored with it, then it picks up and gets really good.
+1...I caught a middle episode out of the blue and couldn't get interested, but after getting the entire BOB/Pacific Blue Ray pack I changed my mind. I thought Pacific was amazing, not quite Band of Brothers, but still nicely done.
Someone mentioned Generation Kill, I watched this on HBO Go, and have to say it was pretty good. I have several friends in military that said it was portrayed really good...a little more drama than real life but that was to be expected. Godfather was a badass!
