This movie didn’t make sense in a lot of parts but I have to correct you on this. She did have the wrist strap on. She then asked her sister to take a photo of her. So she took off the wrist strap to past the camera to her sister. They fumbled it and it was here that the camera fell

"If you drop it, you've gotta go down and get it." Aaaaand, she drops it. Just to get a shot of the shark coming up and eating the camera. So, of course, she's not going to use the wrist strap.

Really? How do these movies get made?

Fair enough!

Hardly sufficient to redeem this movie, but yes, on this point I must stand corrected.

Thanks for your tactful clarification :-)
