Jenna's role is bigger than you would expect for a sequel featuring most original characters, but her role didn't completely take over the franchise as it was for Scream. Not yet anyway. Of course I would have wanted the story to be fully about her character, yet it wasn't, it involves everybody. But at the same time, it is sort of clear that without her performance in the way only she can do, the sequel would not have worked. The other cast members have remarked in interviews that the sequel had to wait so long because she still needed to be born, grow up and become an actress, and that's true.
