*** My 4-star review ***
…and no I didn’t watch it on Fortnite, I have no idea what that is.
I also don’t really have much idea about what TENET is about either, beyond reversing time itself.
UPDATE 13/6/20: NEW RELEASE DATE NOW 31 JULY 2020
What I can tell you is that Robert Pattinson looks like he just stepped out of 60s TV show The Man From UNCLE, John David Washington catches bullets, they’re trying to stop a Third World War which would be worse than Armageddon, and at the very end Washington’s character asks what we all want to know when it comes to reversing time: if we’re here now, doesn’t that mean it never happened?
The trailer finishes with no date but with a line-in-the-sand, COMING TO THEATERS. On IMDB the release date is still 17 July 2020 for the UK and USA. Will it be safe even to go to the cinema then? If they’re open I’ll be taking precautions, because you can never be too careful.

Here’s the synopsis, which I can get behind as it sounds very much like me homeschooling in lockdown, when days have no meaning and neither do Year Three fractions:
Armed with only one word — Tenet — and fighting for the survival of the entire world, the Protagonist journeys through a twilight world of international espionage on a mission that will unfold in something beyond real time. Not time travel. Inversion.
TENET is directed by Christopher Nolan (still the hottest Chris), and also stars Aaron Taylor-Johnson, Kenneth Branagh, Elizabeth Debicki and Michael Caine.
