Dion Wyn’s review published on Letterboxd:
Christopher Nolan's Tenet is more about the concept rather than the narrative, but it doesn't mean that Tenet isn't entertaining. You are submerged into an idea that takes time to contemplate fully. But like most Nolan films, the epic production values help to cushion the inversion blows.
The momentum never stagnates, but at times the execution can become rather flat and repetitive. Robert Pattinson stood out like a shiny penny channelling his inner Jeremy Irons. John David Washington's range is far greater than the character we get. There are moments you see the potential, but I'm not quite sure what Nolan's intentions were.
That's all I will say for now.
