Splice/Headscratchers

So Clive and Elsa's bosses wouldn't let them use human DNA in their gene splicing experiment because of potential moral outrage... But apparently patchwork creatures like Fred and Ginger haven't inspired any sort of protests? and we're supposed to buy that a bio-tech company that's gone that far would suddenly balk at throwing human DNA in the mix?

The logic; she is dubious.
 * It seems to be a legal issue; human cloning is illegal, non-human gene splicing is not. We've had sheep-goat chimeras in real life, so it's not entriely far-fetched. Just for the record, sheep are genetically farther from goats than humans are from chimps.

How is Dren not freezing to death, most of the time? She has no hair and negligible amounts of body fat, yet she can run barefoot in snow, and dip in a pond with no adverse effects. They have an indoor heater in the barn, but it's hopelessly small for a space as big as that, yet she never shows any discomfort from the cold.
 * This is a movie about a spliced human hybrid and you have a problem believing that Dren couldn't have been warm at all.

Really?

So Elsa wanted a child substitute that she could have total control of, that was loving and obediant. Why didn't Elsa just get a dog?
 * I think she already had one...named Clive.
 * That would be what we call a rational decision. Do you see Elsa as the rational sort?
 * This is Truth in Television. (Excluding the whole sci-fi angle, of course)

This is more nitpicking than anything else, but in the montage of Dren growing from just after birth to toddler, Elsa says that Dren is evolving. This is by no means the correct word for Dren's body changing as she grew, and a scientist wouldn't make this mistake.

People keep saying that Elsa cut off Dren's stinger to "dehumanize" her... but a) that would make Dren more human (as most humans don't have tails, stinger or no) and b) she already looks inhuman enough to perch on the near side of the Uncanny Valley. Did the stinger have anything directly to do with it, or was it just the act of strapping her down like a lab specimen for the surgery that was intended to be dehumanizing?
 * Yup, pretty much the latter.
 * not so much that Elsa cut off her stinger, but that before she strips her naked and quite brutally removes the make-up from her face, just to make clear that she's nothing more than a lab rat.


 * Elsa is incredibly chill after walking in on her lover having kinky sex with a genetic experiment. It takes maybe five minutes tops and the two of them are back to discussing pseudoscience like nobody just fucked a terrifying monster. Does she just not care?
 * A genetic experiment which is Elsa's surrogate daughter, for extra outrage points.
