I have seen a Japanese sub movie at Youtube which was moddeled I guess from Das Boot - not reaching it but doing a quite good job I also liked the captain caracter, as being some kind of melancholic or even sad. Also sad I forgot the name. EDIT; I have found the Japanese movie, it is here in GERMAN for FREE:

Also Indianapolis which was decent I think, could be worse really...
Thin Red Line is one of my faves (perhaps in top20) movies, but not for war movies. The amount of memorable quotes or "one liners" in this one almost reach Blade Runner or Dirty Harry levels. [:D] I forgot Apocalypse Now in a simmilar vein, but using other methods to deliver the "memorable quotes"
You will find this here interesting:

Btw. I see some praise in the comments for "Come And See" - I watched this years ago and it left me cold or indifferent. Not in my top war films at all perhaps in the mid range. Still better than some of the "heroic" ones...
Btw2, here another German sub movie, which is decent imo:
