[NO SPOILERS HERE!] Not often I watch a film at the cinema, but this was a definite yes. Since I heard the two words "aliens" and "Spielberg" in the same sentence about a year ago, it was 100% on.
This is not an instant classic of his to be watched for years to come, like E.T. or Close Encounters of the Third Kind, but I think it's right for the times we are currently living in. Things have changed greatly on this subject matter since the New York Times article in 2017, and now "UFOs" are "UAPs," and "aliens" are "EBEs" or "NHI." All very technical and clinical.
For me, this film was 6/10. Emily Blunt plays a vulnerable character who has no idea WTF is happening to her, and she leads the film really well. Good support too from Colin Firth and Colman Domingo. There's some exciting chase scenes — the whole premise of the film — but the occasional cheesy bit too. Wasn't a massive fan of the final scene. I'm thinking, "Why didn't they do that sooner?!" But then the whole film would only be 10 minutes, I suppose.
If you're not into this subject but like Spielberg films, then just grab your popcorn, switch off, and you'll have some fun for over two hours.
But, as someone who has followed this for most of my life, my theory is that Spielberg has been privy to a lot more inside info over the years than he's let on, and has woven that into his films of this nature. I did notice some footage in the film that I've seen as "real" from whistleblowers and documentaries over the years, so you may be seeing some of that mixed in with the obvious Hollywood CGI/AI images. As President Ronald Reagan said to Spielberg after watching a Whitehouse screening of E.T.: "There are a number of people in this room that know everything on that screen is absolutely true."
Apart from the "aliens come from other planets" historical theory, more recent ones are a little darker, like they are ultraterrestrials from other dimensions, our creators, or humans from the future who have come back to fix their/our mistakes. It's a massive rabbit hole to go down there.
If you see Disclosure Day and it piques your interest in the subject more — which I think the film wants to do in an easy, introductory way — check out the work/research of people like Whitley Strieber, Dr. Steven Greer, James Fox, Richard Dolan, Hal Puthoff, Jeremy Corbell, George Knapp, and Ross Coulthart. That's a good starting point.
At the very least, if Disclosure Day has opened up the subject for more people to discuss, do their own research, and take a fresh look, then I think that's a positive thing.
