The Good....
a) I liked the actors. It wasn't Brad Pitt and Jennifer Annison, but hey! The carping and moaning about who's bright idea this was sounded on-key.
"I wanted to go skiing!"
b) Those were real sharks! Eeek!! Check the scene where Susan is drifting asleep -- oh, man! They couldn't pay me to do that! No Bruce the Shark having hydraulic problems here.
The Bad....
c) Gratuitous nudity. How is it that Susan was in the buff, it looked like Daniel hopped into bed naked with a well-timed sheet toss, but later he's doing the Tarzan Dance after a bug -- in his shorts? He had to put clothes on for that? I mean, I got it, he's the hunter/protector just like with the knife in the water, but still.
The Ugly....
d) I've never been on a dive boat. This makes me want to buy not only a safety sausage, but Day-Glo wetsuit, obnoxiously large dive bag, Nixon Halloween mask... anything to make a lasting impression on the crew.
In conclusion, I checked around to find a budget theatre. Big screen is interesting, especially for the night scenes. Just don't expect any Oscars.
