What it's about (no spoilers)
Disclosure Day is an original sci-fi thriller directed by Steven Spielberg, with a screenplay by David Koepp. The set-up is a conspiracy mystery. A cybersecurity expert, Daniel Kellner (Josh O'Connor), is on the run with secrets about alien contact, while TV meteorologist Margaret Fairchild (Emily Blunt) finds her life turned upside down.
It's a fictional story, not based on a true one. Think of it as Spielberg returning to the "what if we're not alone?" question he explored in Close Encounters of the Third Kind.
Why critics are split
On the positive side, Dread Central praised it as a spellbinding adventure about faith, connection and wonder. The film holds about 80% on Rotten Tomatoes.
On the other side, Time Out gave it 3 out of 5 and said it isn't a failure but sits well below the standard Spielberg set for himself. Space.com's reviewer described a close encounter that doesn't quite make contact.
Our read, based on the reviews: the film's ideas and visuals are big, and it works best as a mystery. If you want Spielberg at his absolute peak, you may leave a little disappointed.

Who should watch it, and who should skip it
Watch it if you love Spielberg's alien stories, you like conspiracy mysteries, or you want a big-screen-style thriller at home.
Skip it if you want a tight, short film, or if only his very best work will do. In that case, rewatch a classic instead.
