I thought it might be something like that. I've heard the ROTS-ANH-ESB preference before as well. Personally, I sorta feel that way. My least favorite of the six is ROTJ becuase of the long period on Tatooine and the Ewoks instead of wookiees. The tatooine stuff seemed it should have been a much smaller amount of time than it was, and the other stuff should have been a little more expanded. I mean, the movie certainly serves its purpose and ties up all loose ends, but, it could have been executed and planned much better than it was. It was a satisfying conclusion overall, but was, like other say, too weak at some points and unbalanced.
