That's really cool that you got to see their set and watch them film. It's almost like being in the movie. =)

And as for people who are being stupid and bashing Twilight...get a life. Seriously. Just let the girls day dream. Its not their fault that Stephanie Meyer wrote a book that describes someone you can fall in love with. Edward is the vampire version of Mr. Darcy. Men like that are rare and in VERY short supply. So shut up and let them have their fun and raise their dating standards. =)
At least they are reading and not being obsessed with technology now a days.
