And yeah, the Skrit-Na are obviously just a fun spin on the usual "grays". I actually loved Katherine & Michael's angle on them, they're like these transient junkers & scavengers, not all that powerful/dangerous in the scheme of things, but almost like enigmatic space-gypsies, everybody's given up trying to figure them out, they just cruise around doing their thing.
Frankly any species that kidnaps cows for no reason have got to be Space Gypsies.
