I'm on episode 4... and it frustrates me to say, but its been a disappointment so far
I'm not tied into any of the main characters yet, nor am I feeling anything for the company. I remember catching episode 6 or 7 of Band of Brothers as a off chance on the TV and was hooked right away, went out the next morning and brought the boxset so that I could watch it from start to finish. I enjoyed every episode, even the ones with less gun fighting.
So far, The Pacific has failed to impress me and although I will watch it till the end, I cant see it getting any higher than a 5/10
