Yeah this is a gripe that I have with a lot of contemporary speculative fiction, particularly horror and some science fiction that places its setting in the "contemporary" world.
It's one thing to have individual characters react in "dumb" ways to the threat... The classic "don't open the closet!" thing. But when there's some kind of mass public event, you expect certain things to happen by the authorities.... Questions to be asked, actions to be taken, etc.
When those things just get waved away in service of the narrative, which happens in this movie and many other movies/shows, it really bumps me.
