I am watching the last two tonight. I disagree. The original series (mini TV) was far superior. I thought the original was a factual documentary and edge of the seat stuff. I almost felt I was in the boat and glad I don't suffer from claustrophobia.
This new series is just Girl's Own stuff with tittilation,lesbianism, intrigue,babies and amours de coer.
Stuck on the sea bed ,as usual,and tension when crew work out how to surface? We saw all that in the last episode.
It no longer becomes edge of your seat tension. It just becomes 'same old predictable' Oh well that's my opinion. I still have the original mini series plus the film and the vinyl LP soundtrack. :-)
