Not sure why the focus on whether there is retconning going on or not. Seems like a pointless conversation.

Trailer was meh. Don't much care for Hawkeye when the stakes are so high, so I hope he's not integral to the plot or takes up a lot of screen time.

I'm not sure what the point of the trailer is either. Didn't really tell us much of anything. So Tony survived the Snap but now he's going to die from dehydration or asphyxiation? Sure, lol. Hawkeye is back? Okay, could have used you earlier lol. Do you have an anti-infinity gauntlet arrow in that quiver?

I mean... I'm definitely going to watch the movie but... what was I supposed to get out of this trailer?
