Thanks for your kind words. To let you know the thought process behind the cuts I chose, I found the Fortress scene in IV pretty cheesy with the Elder shouting. "Betrayed .... betrayed ... Betraaayyyyyyeeeeeedddd" so that's why that scene was cut. I felt I accomplished more with the Jor-El memory while Clark pondered things closer to home.
As for the Kent farm (and a line in SIII that was cut), it had to do with Martha being dead. Since she was alive in Superman Returns, I wanted that to fit, so I cut the sequence. While I didn't hate it as a scene into itself, it was incongruous with the new storyline.
Finally, the reason why I busted out Lex when I did was because it had to do with Clark being away from Metropolis. He leaves Metropolis for Smallville and retreats to that quieter life twice in the story, and bad things happen both times. The other time being when he comes to Ricky's party, which gets blown up into the whole "Key to the City" thing. While he's gone the second time, the Terrorists take over the Eiffel Tower and he's clueless about it.
I especially love that Clark isn't lying to Perry when he gets back. He tells him he's been home (still true) and that he was reading Dickens, which I take to be a euphemism for "A Tale of Two Cities." Because this story revolves around Smallville and Metropolis that line really works for me.
