I really love Emma's twilight comment because it is completely true!
But I don't think it was just there to remind us of how pointless twilight is but to also let us know that the R/Hr smooch we've been waiting for won't be along the lines of hot and sexy especially because of how awkward she said it was to film

Though I'm sort of surprised if that was actually what fans were hoping for
This is because, in my opinion, this isn't a bad thing because the way their characters have been portrayed in the film's would lend much better to a kiss that was more sweet, and romantic vs. the steamy and tear-your-clothes-off stuff that you would see in twilight lol Actually, since the house-elf plot line had been cut, I was expecting it to be more gentle anyway cause there would be no sudden "bang" of emotion to initiate the kiss
I for one can't wait to see it and I know it will be my fav scene of the second part
Edit: I also believe that what Emma meant by this statement was that since the romantic side of love isn't the main plot of the series (like it is in twilight) whenever the romantic side shows threw, people get excited as it doesn't appear that often and some audience members are also surprised for the same reason.
Thanks to anyone who was bored enough to read my "little" speech lol
