Superman returns didn't push the button.
Singer created a weird paradox: He played it safe (Donner influences) while making changes that left me scratching my head (the kid).
I just thought that while the plot was good, the execution was very off. There were so many contridictions and plot holes that challeged my suspension of disbelief.
And to me, Gene Hackman's Lex worked back in the 70s. Now, he wouldn't work out espically when he has to go against the likes of Green Goblin, Doc Ock, Ra's Al Ghul, Scarecrow, and whatever.
"The real estate agent from hell" Lex is not much of a threat and to me, it was a mistake on Singer's part to include him in 'Returns'. It sucks when you have the more improved version of Lex now, with the corperate and political ties. And it's weird how Singer picked and chose what he wanted from the Donner films via 'vague history' and he kept "Real Estate Conman" Lex.
