I have wondered about the CGI since the switch to HD, and you're right tonight was much better. I thought the CGI on TDW was quite average (about the only thing I didn't adore about it). So it was a welcome change not to have to make allowances.
With that episode though I would imagine the money was spent elsewhere because the sets and costumes were all quite grand
I guess you are right - and it is only a minor quibble
But in general, I agree and I thought the CGI throughout the two episodes of this story was nice and unobtrusive
