Yeah it did help the following for the books was big and they did show up in numbers for the movie and she really owned the role like a boss and I think she added some more followers with her powerful perfomance and oscar nod too, so it's kind of wierd this sequel isn't benefiting from that as it looks.
Every one was sure this was going to beat THG after RT scores and some early buzz, but they were sure killed off the first day and then they bounced back, but no more room for their happiness now.
