I promise, no spoilers
Suffice it to say, this episode cleverly pays with one's ability to separate 'good' from 'bad'.
I watched this episode from beginning, and try not to read the abysmally, amateurish 'synopsis' one finds (a note to all people who want to write a synopsis; such as that idiot, who's all over IMdB, 'h-gg-' - all a synopsis is is a BRIEF description of the MAIN plot, so fit this episode, that's nothing more than CmdrChakotay's shuttle is shot down in the crossfire if a planet's war zone.
That's ALL. I'd one wants to write more, that's A PLOT OUTLINE.
The synopsis SHOULDN'T tell one the intricacies of a plot. That's what a viewer wants - should - find out in their own, and with am episode like this, the less said, the better.
I must hands it to the terrific wiring, which was able 'alienise' simple English, in such a way that even without makeup and appliances, the group who Chakotay spends most of his time with have a terrific speech cadence.
The old saying, don't judge a book by it's cover, is very true, here.
I world make this episode must-see viewing for ALL children, so they could better understand t this simple idea.
I know I didn't say a lot about this episode - I don't like to spoil things for others, but, I HIGHLY recommend it be seen.
