In reply to Tom Valentine:
”soapy” and unrealistic with regards to the plot. The relationships depicted, on and off shore, committed Nazis didn’t tend to switch sides, seemingly on a whim, and U-boat crews were regarded as a close knit elite of the Kriegsmarine rather than the fractious and mutinous lot shown here.
maybe I’m being unfair, still watching and enjoying it. Perhaps it just suffers a little in the shadow of the original.
