Personally I’m quite happy to see new alien species that manage to fit in with the OT aesthetic. The prequels relying so heavily on previously seen aliens as background fodder was just another example of universe shrinking IMO.
These new rogue one aliens look awesome. I’m not opposed to seeing a familiar alien face here or there throughout the films, but when you start seeing the same familiar aliens more frequently than new aliens it starts to feel lazy and less believable.
Yeah, I don’t want to make it seem like I’m opposed to new aliens. Like I said, just having one or two recognizable faces in the backgrounds of Maz’s Castle or on Jakku would have been plenty.
