What happened?

This movie had already started even before 2:00, which was the time shown in the TV listings.

I watched since there was nothing else on, but it sure was boring while they were in the water. Then there was the scene where the beautiful girl said something about a shopping list for a woman.

Then they went back down again and there was blood in the water, which attracted sharks. The divers had a hard time getting back to the surface.

I don't recall what happened next, but at one point they went to a commercial in the middle of a sentence. Then there was an unexplained jump forward in time.

Then there was that scene with the shopping list comment--AGAIN.

Then they went back in the water. And there was blood which attracted sharks. Then the divers had a hard time getting back to the surface.

At this point I realized I wasn't going to see it all no matter what. Unless this is the way the movie was written. There seemed to be subtle differences this second time around, like we were seeing it from different points of view. Somehow I doubt that.
