I've loved Das Boot since I first saw it as a 6-part television special back in the 1980's. Then I had the movie on VHS tape until it wore out, before owning it on DVD as the TV cut, then the Director's Cut and finally the 6-part complete miniseries on DVD.
I was somewhat disappointed by the sound and picture quality of the DVD transfers (I never saw the superbit version). My main issue was that the sound never seemed to have the ooomph I'd hoped for.
Reading all of the positive reviews about this latest Blu-ray transfer I was encouraged. They praised the picture and sound quality. For the cheaper price of the UK version, where the original theatrical cut isn't included (meaning they can use a BD25 for the second disc) I figured - why not give it a try?
Well, my concerns were allayed. This is an excellent transfer. The picture is crisp - the best I've seen of this film by far, and the soundmix (German/English 5.1 DTS-MA) is fantastic. The dialogue is clear for the most part, and the explosions and depth charges actually boom with convincing resonance. The waves also sound appropriately thunderous during the storms. Best of all are the creaks and groans of the hull, which VERY effectively makes it feel like you're actually in the U96 with the crew. I haven't come across such an immersive soundscape before in a film.
For those of you still on the fence - take it from someone who has watched all versions of this great film: you won't regret adding this release to your collection. Highly recommended both as a film (first and foremost) and as an AV experience.
