An idiotic episode that actually suggests that having Human and Klingon DNA is some kind of internal struggle between two different people. Is that how DNA works? Whenever I watch E.T and cry, is it because I'm losing the battle with my female self. Oh shut up!
Trek has never been very good at complexity. It's all very black & white (especially the culture of a species) and this episode only furthers that view with the idea that a mixed race species is literally two people.
Why would human B'Elanna be incapable of being strong or brave? What? Because it's a Klingon trait. Arghhhh!! Only a few minutes later, Paris (a human) demonstrates that he is capable of those very things (therefore instantly making that plot point redundant).
Then we have the science. People are so quick to mock Threshold but episodes like this one seem to go under the radar despite being equally (or more) ridiculous. If you separate a person's genetic elements, you end up with two separate self-aware personalities?
Interesting to note that Faces (one person is separated into two) and Tuvix (two people are fused into one) were both written by Kenneth Biller.
It's not an episode I enjoy at all but it does allow Dawson to show off her acting chops at least.
Bye bye Durst.
