I knew you of all people would enjoy it, David. From one Lostie, Joshaholic to another...
The dialog they chose is great. Most of it is authentic, but they dubbed in a couple of key changes.
What I like about it is I really get a sense that a Brokie made it. It has to be someone who's seen the movie, because the first piece of dialog they use is this:
Jack to Sawyer: *What* did you do?
Sawyer to Jack: What you couldn't.
Only a Brokie would understand the significance of that. Well, fully, anyway.
And after Sawyer kisses Kate (for the uninitiated - she let him because he promised her he would tell her where Shannon's inhaler was if she did), they dubbed in "Jack..." instead of "I dunno" right before she slugs him. (What I secretly love about that real scene is how he couldn't care less that she just punched him - he's still trying to taste her on his lower lip. YUM...)
