Another Update:
After seeing it...
spoiler follows: highlight to see it
The first 2 thirds of the movie they do not show the shark and when they do, it is, to me, obviously CG'd. I classify this movie as a love story between the rescuer and the researcher because a major portion of it was dedicated to that story line.
