Only one other trailer was as surprising and exciting to see out of SDCC besides Justice League: Thor-Ragnarok.   What was exciting was how the trailer moved our understanding of the movie’s plot forward without giving too much away.  Turns out the Planet Hulk part of the story might not be as dominant in the overall plot of the movie, which is great.  Plus we get more of Blanchett as Hela, which adds a lot of gravitas to the proceedings.
