I watched it with a big grin on my face which got bigger as they showed Asgard and I actually thought "Wow," just a moment before Padme . . . oops, I mean Jane Foster appeared on screen and said the very same word.
There's quite a bit of Loki, some gorgeous scenery and a final clip that, honestly, I think could have done with being cut shot of the punch line - you know, leave something for the film.
That said, this looks great.
