 The episode was criticised by Millvina Dean , the last survivor of the 1912 Titanic sinking , who stated that it was " disrespectful to make entertainment of such a tragedy . " The organisation Christian Voice expressed offence at the religious imagery of a scene in which the Doctor is lifted through the ship by robot angels , believing the messianic portrayal of the Doctor as " inappropriate " ; however , in April 2008 , vicars were encouraged to use the same scene to " illustrate themes of resurrection , redemption and evil " to young people .
