It has been a while since we had a new adventure with Luke, Lea, Han, Chewy, or any character from the original trilogy that did not appear in the prequels. Also all the Star Wars movie with Hamil, Fisher, and Ford have been well received by fans.
Here's hoping that J. J. Abrams does to Star Wars what he did for Star Trek. I think a lot of passionate fans are hoping for this film to do well. If Age of Ultron isn't the highest grossing film worldwide, this will take the cake.
