I think if someone likes a change, they'll try to come up with reasons for why it doesn't contradict. If they don't like the change, they might still try to come up with a creative answer, but half-heartedly. If a series has habit of making changes and they don't like any of them, then their patience is going to have ran out a long time ago by this point.
My opinion on the Gorn is that it was a bad idea to change them, the changes are all eye-rolling, and I'll be happy if they decide to move past them and come up with a better main antagonist.
