Yeah, I liked the gorn episode, but it kinda came out of left field. I mean, it didn't help that in my head every time they would talk about the gorn in earlier episodes I would think of the dude in the green lizard suit, so I had this comical picture in my head of all these people being terrified of a guy in a silly outfit and was not mentally prepared for an alien remake...
I guess I was lucky to have first experienced the Gorn in Enterprise. They were treated as scary and dangerous in a way TOS would never have been able to.
Exactly, actually alien aliens have been pretty rare in Trek. Usually they're stand ins for some human culture or ideology. Even the horta had pretty familiar and understandable motivations. These gorn are pequenino tier alienness.
