It's not quite what I'd hoped for in terms of giving greater insights into the plot, or showing Luke (and Leia didn't even get any dialogue either), and is mostly just a longer teaser built on the framework of the previous two. That being said, this trailer hit all the right notes in terms of getting me excited for the film and for establishing a nostalgic connection with the OT.
I love the mirroring of Han being the one ignorant of the exploits of the Jedi in ANH and now being the one passing the lore on to Finn and Rey. That narration by Ford gave me chills. Especially when coupled with the absolutely beautiful remix of the Han and Leia Theme from TESB that manages to be full of love, hope, loss, and regret all at the same time, which would make sense if some of the rumors about what the characters have been through are true.
I already knew they were doing yet another superweapon in this, so that wasn't unexpected. What was unexpected and slightly disappointing is that in its purpose and now its visual appearance (as seen on the poster and in the trailer) it's such a blatant rehash of the Death Star, just one that was clearly conceived with the notion of "How do we make the Death Star bigger and flashier?" So now instead of a space station, they just carved out a superlaser directly from a planet's core and even included trenches for the Resistance to fly down.
It's kind of hard to take Kylo Ren seriously when his facemask looks like the furrowed brow of a bulldog that's joined Daft Punk.
The shot of the Falcon going into hyperspace gave me goosebumps. I loved the outside perspective on it and the new transition from the streaks of light to the Dr. Who tube. Brilliant.
I like Finn's arc about being created to fulfill one purpose as a Stormtrooper and wanting to grow from that and find his own path in life. And Rey's arc seems to be about having a greater destiny that she must accept herself. Pretty standard Hero's Journey boilerplate, but there's a reason it works.
The flight and battle shots were just stunning. I think the combination of practical effects with CGI enhancements that allow the camera to move in and out of the action at will in long continuous shots will possibly give this trilogy a chance of surpassing RotJ in terms of having the greatest space battle ever committed to film. Just the weaving shots around the Falcon and the X-Wing versus TIE dogfight over the superweapon planet alone were amazing, and there's supposedly a huge space battle as well.
So the trailer was quite everything I'd hoped for, but it was still very effective in building up anticipation for the movie in two months. I can't wait.
