All that said, trailer looks fun, same tone as Homecoming which is a treat, Jake Gyllenhaal looks great as Mysterio and should probably never shave that beard.
Thoughts?

I'm an Engineer and built the video game community Cheerful Ghost and text based mini-MMO Tale of the White Wyvern.
I will be glad to get away from saving the galaxy and back to saving a city, or a person, or something smaller scale.
And as evidenced by my face, my personal rule of thumb is that if you can grow a proper beard, you should probably never shave that beard.
The snap could be permanent. Could be a totally different universe.
Damn that would be a hell of a twist. I like it.
Yeah, there's got to be some sort of twist to this. at least I hope. A current major theory is that Cap or Iron Man die (and the other retired or something) in Endgame, and in the end of this trailer, one of the students compares Mysterio to Thor and Iron Man, but no one seems sad that Iron Man and Cap are gone. (Maybe I'm reading too much into that though. I suppose Cap was a fugitive between Civil War and Infinity War, so maybe the kids dont miss him)
Is Endgame going to be Back To The Future 2, where the avengers time travel and we get to see infinity war all over again?
I hope so!
