I kinda liked it. As much as the Pacwar is my favorite in ww2 history, for some reason the movies of it come out flat. Hope it gets better.
I had the same initial impression while watching. My opinion improved as the first installment progressed.
Despite the producer's explicit statements that Pacific is *not* BoB in the PTO, I think many viewers are looking for that comparison, regardless.
The Thin Red Line fell victim to the same fate when movie-goers went in expecting to see SPR in the PTO. TRL, by just about any critical measure, makes SPR look like a turd; yet one is clearly more popular than the other.
Thus far, my biggest Pacific gripe is the lack of character development but, again... that's based on BoB comparisons I'm telling myself not to make...
