This was the worst thing about dredging up the Donnor-verse instead of rebooting with Returns was the Land Grab Luthor of the 70/80's pre-Crisis Lex Luthor.
When he shows that map of how his plan is to create the island AND then sell his land to the wealthy the silliness is so evident. He's going to flood Western Europe, Eastern USA and most of North Eastern South America where the largest part of the worlds wealth resides. Great plan Lex. So that leaves Russia and Communist China I'm sure they'll just roll over for you. Great plan Lex.
Returns Luthor should've been the post-'86 Crisis one that was the corporate megalomaniac. That portrayal had successfully been incorporated into Animated Shows, Lois & Clark and Smallville. Yet for Superman Returns they revisit an outdated portrayal of Luthor. WTH.
