 FAIR: All accounts of the sinking by survivors report that the  lights went out, flickered back on for a second, then went out for  good before the ship broke in two, all of which is correctly shown  in the movie. In fact, many survivors disputed that the ship broke  apart at all before sinking. Naturally when the lights go out that  quickly not everyones eyes adjusted to the dark fast enough. Even  though it has since been proven that the ship did break before  sinking, one would imagine that there would be no room for dispute  if the lights had stayed on until the ship broke.
