Quickly I began cheering for the shark .
Why you ask ?
Because the whole plot feels false and contrived. It tries so hard, so very very hard, to make you care about the characters and their relationships. Yet fails utterly .
I think you're suppossed to feel the warmth of their relationships and see them as real people. So you can feel their loss when the Shark has dinner.
Instead, it is portrayed in such a shallow and cringeworthy way, that you hope the Shark has seconds plus a good dessert .
The film lacks any relevant information for you to give a damn, except perhaps to hope the shark dines well on the blandness.
Whatever is in the water, it aint a good story.
