I saw the miniseries version for the first time today. Perhaps a bit much and long for one sitting.
However, the (spoiler alert)
Convoy attack - dive, depth charge, Johann goes mad, repairs, and burning tanker section being over a hour is amazing in the miniseries version. But I think for most cases, I prefer the directors cut.
Though I do need to get in on blue ray, but I will wait till next paycheck, spent way too much money this paycheck.
That, and I was watching it with a friend, and I had warned her that it not a "happy ending film" and she was sure that the poor crew dies at gibraltar.
The actual ending had her screaming at the TV.
