Deep Blue Sea is yet another in a long line of movies that presents us with sharks as the devil incarnate. This time a group of them has been wrangled into an offshore pen where a team of scientists is attempting to extract chemicals from their brains to manufacture an experimental Alzheimer medicine.

The problem is that the sharks' brains aren't large enough to produce enough of the chemical so the lead scientist, played by British actress Saffron Burrows, tinkers with nature a bit, making their brains larger. Naturally, the Law of Unintended Consequences kicks in and the sharks use their increased grey matter to bring down the house -- literally.

The first time we saw Deep Blue Sea, we didn't like it at all. The portrayal of sharks, yet again, as little more than horrific eating machines at a time when their populations are being decimated, was the movie's biggest crime but far from its only one. All of the computer-generated images of the sharks underwater look like something you'd see in a bad computer game. The sharks in Finding Nemo are far more realistic. The Saffron Burrows character is especially unlikeable. And the rest of the characters are only marginally better. Upon further review, though, one of us, Jerry Shine, decided he kind of liked the movie. The rest of us still hate it.

That being said, Deep Blue Sea does have a few things going for it. Characters that you assume are going to make it -- or are at least going to survive long into the movie -- don't necessarily do so. Characters that you assume aren't going to make it, do. And just when you think there isn't going to be any gratuitous showing of flesh, Burrows strips off her wet suit to stand shivering in her undies.

There's a fair amount of underwater footage and some of it's good. Surprisingly, the footage of the sharks out of the water is very good. All in all, though, this is not much of a movie, dive or otherwise. But it may hold your interest if you set your expectations low enough.
