Except for the first movie, I hardly noticed any changes in the series. That's why I don't understand why people make such a big deal over it. I know the first movie had the most changes, but sheesh. It's a movie from 1977, cheap CGI (doesn't look cheap to me, but...) is an improvement over some of the cheap effects in the original.
The stormtrooper still runs into the door, Vader's helmet still blows in the wind, ewoks still blow.
