I would not call it terrible. The last 10 min comes close to terrible though
1st 30 to 40 min is great stuff. Next 30 is OK and good enough. Had the ending been great this could have been an all timer for me. It was good enough for me to purchase in the future because it still is one of the better Shark Films. But It's not as good as The Reef, Open Water, and of course JAWS (was not expecting it to be). I liked JAWS 2 more also So I guess that makes it the 5th best shark movie ever
The whole movie was solid but the ending is what will have me purchasing the blu-ray! Open Water is "better" yes but it's a little too "real life" and depressing to watch over and over (and yes I realize that was the whole point of it.) I don't put The Shallows in that category, to me it's more like 10 Cloverfield Lane where the majority of the film is grounded in realistic peril but then the heroine organically becomes this bigger kind of cinematic hero. As I said in my review if you rate it only as a "woman vs. nature" film then yes it fails. But as a "woman vs. monster" movie with a very grounded build up it was absolutely thrilling IMO.
Not just any great white but the smartest Great white ever.. Bruce had nothing on this Serial Killer mentality this shark possessed. Apparently it's very territorial about it's huge food source. So much so that it ignores the giant food source
Now now, it might have been more obsessively territorial than the first Bruce but it had nothing on the sharks from Jaws The Revenge or Deep Blue Sea.
That being said I knew that the ending would be a polarizing aspect of this movie just like it was for The Witch and 10 Cloverfield Lane.
