Overlooked, of course, only in the sense that I didn't see it until recently . . . although it didn't take me as long to catch up to it as it did the companion series BAND OF BROTHERS.
THE PACIFIC is set up similarly to the earlier series, following a group of real-life characters through the war in the Pacific, starting with the battle for Guadalcanal and following on through to the beginning of the post-war era. It's based primarily on two books written by the participants, HELMET FOR MY PILLOW by Robert Leckie and WITH THE OLD BREED by Eugene Sledge. I own both of those books but haven't read them yet.
As in BAND OF BROTHERS, the battle scenes are brutal and graphic and very well-staged, and the acting is good all the way around, especially James Badge Dale as Robert Leckie and Joseph Mazzello as Eugene Sledge. Overall, though, this series suffers a little in comparison with the earlier one. Admittedly, BAND OF BROTHERS is one of the best mini-series ever made, so that comparison may not really be fair, but it's unavoidable. There are three main storylines in THE PACIFIC, including many scenes set far away from the action in Australia and in the United States. That jumping around in the plot, along with the romances in which several of the characters become involved, can't help but make THE PACIFIC feel like a really well done war soap opera rather than a recreation of history. I also missed the narration by actual veterans that figured so prominently in BAND OF BROTHERS, but again to be fair, most of the participants in THE PACIFIC, including all three main characters, had passed away by the time the series was produced.
So I feel bad about quibbling over these points when I really did enjoy THE PACIFIC and am glad we watched it. If you enjoyed BAND OF BROTHERS, you definitely should give this one a look, too.
