After this teaser I'm more excited for The Rise of Skywalker than Endgame or any other movie this year. It's the end of the Skywalker Saga but not quite end of the Star Wars franchise. I've heard news from Lucasfilm and Disney that after this movie they are going to take a break from making films and focus on TV shows on the new Disney+ streaming service. I like the idea of great Star Wars shows but had hoped they'd have figured out how to roll out a new film each year.
That said, let me know what you think of The Rise of Skywalker teaser and i'll put my spoilery thoughts in the comments.
