I don't see that as any misrepresenting on their part but a not paying closer attention on your part. The angels went to Sodom to seek rightous for Abrahams sake. Lot's resposne was to help them despite the dangers. Lot was tested by them. The fact the angels had no fear wasn't the point. Lot's response to their pleas was the point. Lot's response plus for Abrahams sake GOD spared Lot.
Next is the fact the movie was not despite what some assume written by The History Channel rather History Channel was the only one who would show it. They had a finished product as I understand it and History Channel agreed to show it.
This isn't anymore off the mark than what a Sunday School teacher might use to illustrate The Bible. Remeber this movie is aimed at the general public not just believers. There is plenty of time to study deeper and learn but first the seed must be planted.
Some want the movie to where only those who have read and study The Bible for years would appreciate it. The movie is aimed at trying to reach persons from all walks to get them to consider their relationship with GOD. Believe it or not many, many, persons have received Christ and the persons help lead them to Christ did not even have a Bible in hand. The message {the seed} is planted, The Holy Spirit if the person will listen and allow brings conviction or the knowledge of sin to the person, guides them, and brings the lost too salvation if the lost submit.
