I saw this movie on opening day, and I will admit it, it was great. I had my reservations going in and I completely expected it to be mediocre. I was wrong. The comedy was great and there was a good mix of that along with action. I loved the new characters and enjoyed seeing the old ones. My only problem was that the plot was thin, but they needed that to focus on new characters. If the plot would have been huge with throwing new characters in, I feel it would have been too much. Overall, great movie. Definitely in the top 3 star wars movies for me.
Final verdict is an A-. I fully expect episodes 8 and 9 to be the best of them all. I literally can't wait. Such a good start to a new movie series in the star wars saga.
