This is like a cross between Hollow Man and Alien, whereby a cross breed of human and beast results in the formation of Dren, a young feline form that is ageing at a rapid rate. Like most females it demonstrates a very unpredictable but alluring nature that intrigue the two scientists that helped create it and continued to allow its development. Unlike most women though, this one has a literal wicked sting in its tail in addition to the characteristic of being able to change sex as part of its development process. Such a rapid transformation then becomes well outside the domains of the scientists control, meaning their undercover secret is at risk of being exposed. Admittedly the enticement of achieving such a scientific breakthrough has seduced the two lead characters, whose passion for their creation gets even stronger as they become engrossed in a parent like bond (quite frankly to the point of a gross extreme). I'm not normally a fan of heavy sci-fi features but this was quite an original storyline, and the subtle horror of it kept me intrigued. It wasn't predictable in the direction it was going to go, which is a characteristic that appeals to me, but I guess at times it become too far fetched for its own good. The on screen relationship was slightly odd between the two, and it felt like more of a brother / sister combination than them being partners, but given the concept of this, perhaps I was reading too much into the inbred theming. I enjoyed it as a one off, but was not completely sold by it, and certainly wouldn't rush to see any sequel or similar adaption if it were to be released.
