I -liked- the trailer, but that scene with Noctis and his dad definitely went on a little long.
Best part of the trailer was the first half and the last scene with those shapes appearing way up in the sky. Also loved the music, and like Obsidian said, I like the visual of the world, especially the part where Noctis's dad is holding this beautiful sword while standing outside of a car. It somehow works, in my opinion.
