I also can't believe they held back having Luke all over this movie. I love how they did that, introduced him at the very end, and held all that back for future films. I also love how they held back on most other characters from the past. It was a great decision to focus on all of the new characters, and let me say that they did a HELL of a casting job with every single one of them! We had Chewie and Han and that was all we needed, and that was flat out needed to tell this story of the film.
I loved it I'll say that. My second or third favorite Star Wars film ever, and just one of my favorite experiences in a theater in my life.
I loved the style of lightsaber battles too! Thank God they didn't bust out what we saw in the prequels. I don't care the reason for it, it's weaker now or whatever, but I'm so happy that they went with a more realistic style.
