The only real "sin" of this series is its low budget and not-great set accuracy. But I can't fault a made-for-TV series in 1996 for it.
Specially when in 2012 iTV made a 4 part series with a far bigger budget that was 10 times worse than this one. Had this series had an HBO-today type of budget, there's a chance it would have seriously contented with Cameron's version of Titanic.
I really hope to see it on Blu-Ray soon.
