Corrected entry: Fitch, who professes qualifications in biology, genetics and biochemistry, says that they made Sil female because she's a natural predator and so she'd be more docile. He should retake his finals. In every single species of predator on earth - every single one - the females are the hunters, aggressors and killers. The males may be socially dominant but they are the 'docile' ones. There are no exceptions - and humans are not predators.
Corrected entry: After the man takes her from home with him and they are both in the swimming pool at his home, she whips off his trunks begging him, but in the next part when he's fighting her off and he's later seen floating dead, he has his trunks back on.
Corrected entry: In the scene where Sil (as a young girl in the lab's container tank) realizes she's being gassed with cyanide, she escapes by diving through the glass enclosure. The gas escapes along with Sil. The lab techs (who are fully protected with Hazmat Suits) fall down dead when the gas reaches them. Shouldn't the suits have protected the lab techs from the gas? That's the whole point of wearing Hazmat material, right?
