Of course not. It's your threshold!
But why? Why is a difference in, say, the bridge, not comparable to a change in actors, however the actor looks? What makes it acceptable to change one and not the other? It's a genuine question. What makes each of us, individually, comfortable with one change and not the other when they are, essentially, of the same nature?
Well, I am a bit weird, I’m quite content to admit it.
Interesting question, and I think it’s because as human beings we, generally, connect to other people more than objects. To me, the sets are just a backdrop. But characters you connect with and you kind of expect some kind of continuity; for them to be recognisable. I don’t have a problem with recasting so long as the character is recognisable (Ethan Peck, for instance, I can buy as Spock because he looks the part and actually has something of Leonard Nimoy about him). If this is the same universe as TOS, and I asked you to describe Kyle now, how would you reconcile the fact he is now both Caucasian/blonde haired and Asian/dark haired? It confuses my poor brain. If I take it to be a reboot or alternative universe, no problem.
