If you're looking for a holiday movie to watch, this has become a family tradition for us.
I think it's wrong about the wise men being at the manger, and it adds things, as movies almost have to. But there is obviously an intention of drawing out the characters biblically when they add stuff. Except the wise, who are just fun. I especially liked Herod. Very well done. It draws out the coming antithesis and opposition very well.
It has an intense scene around 2:00-3:00, not for younger (10?) viewers.
