Little late for this, too.
In looking over reviews and comments on the 1953 "Titanic" it seems that everyone but those on the Titanic forums on this website thought the movie was great, mainly due to the acting of Webb and Stanwyck.
There was little or no mention of historical accuracy.
The over-dramatic sinking finale, the singing crowds, the siren, the blasting of the whistle, etc. The inaccuracies are so apparent that there’s no need to bring them up
