^ It could simply be because watching Imperial Japan blow the living hell out out of people is not a enjoyable time at the movies for a lot of folks.
Don't get me wrong, though, that's not to say it isn't a decent film. I loved
Yamato, for example, despite it taking on similar historical material. The difference though, is the date of production.
Yamato is a modern film, produced in retrospect long after the full nature of Japan's WWII campaigns had been revealed to the world.
The War at Sea from Hawaii to Malaya was produced in 1942, and so it will always carry the distinct aura of a propaganda film produced while untold tortures and atrocities were being committed by the Japanese military in East Asia. The average Japanese soldier was most likely unaware of this, of course, and so we should be careful not to demonize them along with their leadership. However, we shouldn't expect film buffs to be able to totally quarantine that knowledge in the back of their minds while they watch a war film, either.
One thing we can all agree on? The special effects in
The War at Sea are absolutely incredible. Check out this clip:

Tora, Tora, Tora.
