Doesn't change my point. We expect trains to move a certain way. If you're going to change it, do so for a reason, not just to excuse lazy CGI.
I agree the CGI was rubbish. But not because of the movement; it was just poorly rendered. You might expect futuristic space trains moving faster than light speed on hyperspace ribbons to move in a certain way, but I'm afraid I'm not included in that "we" you mention. Futuristic space trains moving faster than light speed on hyperspace ribbons can move any darn way they please, as far as I'm concerned!
