SQUEEEE! I watched the trailer yesterday afternoon in the car, on my phone (don't worry, I was sitting still in a parking lot). The sound was good because of my car speakers, but it was unfortunate that my first experience was on my small phone screen.
So, I watched it again at home on the big television screen. So much better.
Needless to say, there is lots of speculation about what much of the trailer included. What does the title "The Rise of Skywalker" mean? What does Luke's voiceover mean (the bit about "no one ever really leaves")? And who is laughing at the end of the trailer (most believe that it is Emperor Palpatine)?
More will be revealed in the months to come, I'm sure. But for now, I'm reveling in the excitement of a new Star Wars movie!
