I did like some of the stuff he added. Most notably, I really like the extended scene of Luke and Obi-Wan entering Mos Eisley.
It might have been cool visually, but I really missed the eerie, desolate feel of the place in the original version.
Instead it became just as busy and overcrowded with aliens and little flying doodads as all those OTHER cities we saw in the PT.
It didn't blend in as well as it could have with the rest of the movie but Obi-Wan did describe it as a "hive" which would seem to imply more activity than we saw. They probably just didn't have the money or resources to portray it that way. I'm not saying it's perfect but I liked seeing more of Mos Eisley.
