The 35mm version of AOTC doesn't have the line "to be angry is to be human". Do you think that the digital version adding this line was a good change or a bad change?

As far as I know, the digital version didn't have that extra line either. It was added for the dvd.

It's worth noting that the "I'm a Jedi" segment of Anakin's reply was in one of those early teaser trailers for the movie. It was probably in an earlier edit before it was deleted for the theatrical release.

The question, indeed, is why George felt it was so important to have that moment put back into the movie.
