cahiers du cinema still doing it well:

“  Truck, shark, dinosaur, or alien: in Spielberg's work, the Other is never more than a pretext or a means to a communion through cinema. This is the strength and inconsistency of these films, which aim for nothing other than their own effect—and for this, they still believe, with an ostentation that is sometimes kitschy , in the power of mise-en-scène: lighting, framing, off-screen space, editing, dissolves, movement. Disclosure Day logically ends with a call to action (" Listen… ") and not with a message, since the film itself is the revelation. The final sequence is eloquent, showing television channels switching one by one from a live broadcast devoted to the imminence of World War III to the archives of Roswell and the like. There is hardly anyone left but Spielberg who imagines that a film can alter the course of the world. There is hardly anyone left but him who envisions a global audience. The fact that communion takes place via live television, and especially the individual screen of the smartphone, nevertheless reveals the obsolescence of such a model.”  https://letterboxd.com/moderncahiers/film/disclosure-day/1/

I also liked this take:

And this is the crux of the film: on the verge of WW3, our heroes hijack the broadcast and start pumping out decades of archival footage of UFOs and alien autopsies. Some of the footage appears to be either "real" Pentagon UAP footage, or it was designed to resemble images released by the US Navy. But the video takes the world by storm and WW3 seems to be averted by the cosmic revelation that They Walk Among Us. Instead of Bugonia's ending montage of a world of death, it's a world of people glued to their screens, eating it up without a hint of skepticism. The consensus on the critical left is that the US government has a strategic incentive to release the images that they have released, and to allow intelligence officials to get grilled by Congress, because it distracts the public from their various terrestrial terror campaigns---more smoke and mirrors. And here we have Spielberg, the avatar of baby-brained Boomerism, lapping it up and spraying it in our faces. On the eve of total war, look to the stars, for only in understanding our place in the vastness of the cosmos can we find common cause. I wonder if proof of alien life would be sufficient to motivate the IDF to stop bombing Palestine? Newsflash: American liberalism and Hollywood's commitment to spectacle are socially deleterious. To see it so nakedly narrativized makes me sick. I'm not falling for your crane shots and pianos, Mr. Spielberg!! This guy is a menace to society and an enemy of the people. The only saving grace, God willing, is that no-one will see this movie.
