Re: There's no such thing as "great CGI effects".
Great CGI effects are when you do not notice them.
Yeah, and that's the thing: they're so very easily noticed. There's absolutely no mistaking, say, Lake Town in The Hobbit, or the droid factory in Star Wars ep. 2, or the action scenes in the recent Mad Max trailer, or anything in any Marvel movie ever, for reality. It is state-of-the-art CGI, and screamingly obvious.
"Downtown Abbey" have a large post production crew removing artifacts like cars
That's no doubt true, and perhaps it's easier to remove things undetectably than adding things undetectably. Certainly fake carriages and city scapes are easily detectable in period pieces too.
