If you don’t already know how the pieces connect, it’s a fairly hard-to-follow trailer. Things fly by so quickly it feels deliberately obscure. And there’s no splashy central image or event to grab onto.
Of course, it’s a teaser trailer aimed at getting the Marvel faithful to go through it shot by shot* and not aimed at noobs at all; the “explain what this movie is about” trailer will come later.
*Watching it again this morning with the sound off I finally noticed the shot of the Skrull with the ears, which I totally missed the first time. And I also noticed that a bunch of the shots are done with a telephoto lens to give it that extra 90s feel, which I thought was a nice touch.
