Brilliant series - also watched it first time around in my teens. I think it was one of the first drama series that had a profound impact on me.
I think it's production values were pretty good for the early 80s - especially as the first two episodes were filmed in Singapore. The rest was on location in Dorset!!
It covered many women's issues which were really radical for the time - periods and lesbianism to name just two.
It certainly started me on reading far more deeply into the subject - I have a whole collection of books written by women who were interned by the Japanese (along with the aforementioned book about the making of the series!) They are often overlooked in WW2 history - seen as privilaged women who were too busy partying to notice the invasion. Their biographies tell a very different story.
If you every visit the Imperial War Museum in London, they have a quilt on display which was made by such women.
I actually think it would be great for a re-make (done properly) - with today's high quality production values and the ability to speak more openly and in-depth about some of the issues it raised, I think it could have the potential to be amazing.
I also think, comparatively to other areas of WW2 history, they are little known about and it would bring them to a whole new audience.
