The not speaking english is hard since it's hard to interact with them from a storytelling perspective. Enterprise half heartedly tried this for awhile before finally just dropping it. With CGI these days? The truly alien creatures are possible, now, sure.
I even preferred the Gorn on TOS to the CGI one on ENT.
You have Gollum in Lord of the Rings and this was obviously a very costly enterprise. And he was a mad bastard so you expected him to be not quite right. If you wanted say Spock who appeared in practically every scene in TOS to be CGI'd then he'd have to be spot on for you to relate to him.
I don't think we have that technology now but we may have a more realistic cheaper CGI in the future.
