The History Channel's "One Hour over Tokyo" and "Unsung Heroes of Pearl Harbor" provide depth that Bay's movie lacks, and Charles Kiselyak's interactive timeline is arguably the finest feature included, providing an in-depth historical perspective on U.S.-Japan relations. Even a brief reenactment of a Pearl Harbor nurse's journal is moving in a way that Bay's film can only try to be, while the "Interactive Attack Sequence" provides a multifaceted exploration of the entire production process (a highly educational feature for aspiring filmmakers). All in all, these four discs offer an admirable balance between Bay's technically impressive but ill-conceived epic and a thorough, fitting tribute to those who endured hell on that fateful Sunday in 1941. --Jeff Shannon
