> but it’s weird for my boss to make that message the focus of what is ostensibly a corporate team-building event.

Having been a manager: I bet your boss didn't want to be there any more than you did. They were forced to do corporate team-building and they recognized the absurdity of it all.

So they tried to come up with something entertaining that they could claim was passably work-related. They were trying to do their best by you within the constraints of what was mandated by their job.

This looks like a nice gesture. You are too occupied viewing your manager as "the other" to recognize when they were trying to bond and do something nice for the team within the constraints of their job.

You're lucky. At corporate team-building retreats I never got to watch any fun movies. One had us listen to lectures by a manager whose primary experience was as a little league coach and who thought leading his team was the same thing. The other involved the manager giving us a psychology test of his own creation and trying to lecture us about what he thought our learning styles and weaknesses were based on all the different self-help books he read.

Totally valid that my boss probably didn’t want to be there either, but for context this was circa 2008 Google where “offsite” meant “go spend company money to do something fun.”

Alternatives were literally things like going to Napa or an amusement park or go-karting. Or if you really wanted to watch a movie, the options were all other movies. Why pick the one that digs at the tenets of your shared reality?
