rawls:
Ok...Here's my humble and somewhat angry take on this. Sharks are not out to eat people and the number of shark attacks on people is infinitesimal.
Tell that to the men of the USS Indianapolis many of whom were victims of the oceanic (Pelagic) white tip shark.
Now to reality... This from a shark studying friend of mine;
First, the sharks used in open Water were black tip and reef sharks and were shot in the Bahamas (or Bermuda I forget which and am too lazy to load the DVD to find out). These particular sharks, were in fact quite used to humans, as that are part of a school that has been excessively used for "recreational shark dives"....these should not be confused with true Pelagic sharls.... like the blue, white tip, white, the thresher and mako; all of these with the exception, of the bull and the tiger, the above have the most human attack numbers.
Pelagic sharks live in the open ocean, not on reefs and other shallow structure, and tend to look as anything as a viable food source, and have little issue scavenging carrion, or living prey. Tagged fish have been tracked crossing entire oceans during their migration and have been observed eating any living/or dead for that matter, creatures they come across during such migrations
Now back to the movie...yes it was an opinion as to what could have happened after the two were left behind...to date no one has argued that the couple did not return with their charter...willingly or accidentally.
My wife and I watched it, and as a husband/wife dive team we found it amusing...especially the she blame/he blame game, bickering, and eventual support for one another.
The film was more about the breakdown of the human physique under stress...and with that goal in mind...it worked IMHO. When was the last time you saw a flick where the full range of emotions, and dynamics between a married couple are examined in such as barren manner?
Most of it's "diving" related footage was bogus...too numerous errors to mention, but lets start with no SMB, whistle or any of the normal safety gear a responsible diver carries in open water..
The night shark attack, while believable, leaves one wondering why only the husband was attacked.....the wife makes it through without getting bitten...highly unlikely...given their proximity to each other.
As to the "evil" nature...I did not see any attempt to anthropomorphize the sharks. They were not portrayed as evil....just a natural predator doing their thing. Jaws on the other hand...well even Peter Benchley has apologized for writing that stinker.
I, like Catherine, like the flick. the ue of the hand camera in the water gave it a raw, yet intimate perspective, and made it look more like a documentary, than a Hollywood romp.
Anyway, it won't win an Oscar, but was not nearly as bad as Into the Bra...umm Blue or the Cave.
