I'm not looking for a one paragraph summary or vague mentions of "more Jor El", but for a detailed, thorough analysis from someone who knows Superman by heart, who saw the expanded cuts, and who compared them (saw, personally - since there are e.g. some analyses of missing scenes from the script, laserdisc, etc., etc., with someone guessing what extra scenes should be in the Salkind version). Something such as e.g. this analysis and comparisonr of the Cliffhanger workprint: http://www.yourfilelink.com/get.php?fid=100625

If there is anything like that out there.
