Good clean fun. 
 It's horror in all the grand traditions. Want B-Movie sensibilities? Check. Want monstrous mermaids? Check. Want a Sy-Fi film crew staging a mermaid expedition to get torn apart by the real thing? Check. 
 Did I say Sy-Fi? I mean Imagine Network. Sorry. I didn't mean to make any disparagements. We're NOT trying to make a statement about anything. Truly. This is just a good clean horror, all fun, no message. Really. We certainly don't want to ruin our chances to get a made-for-tv movie based on this novella by the Sy-Fi network. It's perfect for it. 
 Who survives this tale? The lawyers. It's pretty classic. 
 Of COURSE the lawyers survive. I mean, out of anyone to come out of the Mariana Trench, the greatest predators are NOT the mermaids or the sharks. 
 *sigh* If only there had been an appearance of Aquaman to save the day. That would have been PERFECT.
