I remember how excited the episode I trailer made me. Just the whole experience. When the STAR WARS appeared on screen at the midnight showing, that was one of the few times in my life I involuntarily screamed with excitement. It's too bad it's just not there anymore. I saw the trailer in the theatre, it was good. It even looks like a good movie with a lot of substance to it. But I'm just not motivated.
It's hard to judge the trailer out of the context of the whole Star Wars experience.
