I stopped watching this movie after this scene (which is pretty close to the start). The way the scientists and world leaders were discussing how to communicate was just so absurdly shallow that I couldn't take the movie seriously.
Like, I can easily suspend disbelieve to watch a movie about aliens doing all sorts of weird things that are inconsistent with basic physics; but it just really bugs me when a movie makes a point of bringing together the smartest and most capable people to solve some issue, and then utterly fails to show even a faint glimmer of that knowledge or intelligence in what they do. I reckon a random person picked up off the street would do a better job of first-contact with aliens compared to these clowns.
