Hi Robert,
Not at all, surely it's not that difficult to be historically accurate!
The Zeta-Jones film might have been better if it had been produced in its own right, but it was hugely overshadowed by the James Cameron blockbuster the following year.
Also, maybe I just got a bad version but I distinctly remember the quality of the film itself in both the 1996 mini-series and the film S.O.S. Titanic being extremely poor.
Cheers,
Adam.
