Detailed Reviews:
From the New York Times:Gorgeously shot across multiple global locations and pivoting on an elastic, time-bending conceit (more on that later/earlier), the film is undeniably enjoyable, but its giddy grandiosity only serves to highlight the brittleness of its purported braininess. This would hardly be a criticism of any other blockbuster. But Nolan is, by several exploding football fields, the foremost auteur of the “intellectacle,” which combines popcorn-dropping visual ingenuity with all the sedate satisfactions of a medium-grade Sudoku. Within the context of this self-created brand of brainiac entertainment, Tenet meets all expectations, except the expectation that it will exceed them. Forgive the circularity of this argument: it’s a side effect of watching the defiantly circular Tenet.
From The Guardian:No wonder Christopher Nolan thinks Tenet can save cinema. That’s a doddle compared to the challenge faced in his film, which, we’re frequently reminded, is a proper whopper. Prevent world war three? Bigger. Avoid armageddon? Worse. To spell it out would be a spoiler, but think 9/11 times a hundred, to quote Team America: World Police, a film Tenet faintly resembles. The fate of a few multiplexes is small fry.
Lucky, really, because Tenet is not a movie it’s worth the nervous braving a trip to the big screen to see, no matter how safe it is. I’m not even sure that, in five years’ time, it’d be worth staying up to catch on telly. To say so is sad, perhaps heretical. But for audiences to abandon their living rooms in the long term, the first carrot had better not leave a bad taste.
From The Telegraph:Feeling your heart and brain race to keep up is a significant part of the fun here, and in that unique and unmistakable Nolan-esque way, there is a series of exhilarating mental snaps whenever the two temporal perspectives intermesh, like the teeth on opposite sides of a zip. As for the parts you won’t and can’t, appreciate first time around – well, rewatching is always an option. If Tenet does revive the British box office, as cinemas are praying it will, that will be down in no small part to the fact you have to see it at least three times to be sure you understood it [...] This is a film that will cause many to throw up their hands in bamboozlement — and many more, I hope, to clasp theirs in awe and delight.
From Indiewire:Nolan is not invested in the meat-and-potatoes plotting of lesser mortals. He trades in big-picture concepts, and his latest is tried-and-tested: a device that reverses matter. Careers too, apparently. Tenet revisits the terrain of 2000’s Memento with more money and a protagonist — sorry, Protagonist — who, in tracking and repurposing that gizmo for good, masters the flow of time rather than falling prey to it. Yet plot-wise, Tenet has more in common with Minority Report than Memento, even as it lacks the sophistication to make that route worthy of exploration. An insinuating mid-budget noir has been punched up into a bet-the-house studio actioner; interminably PG-13 shootouts and fistfights replace those tangible, haunting Post-Its and Polaroids.
From Variety:[Nolan’s] musings are rooted more in physics than philosophy or psychology, with the film’s grabby hook — that you can change the world not by traveling through time, but inverting it — explored in terms of how it practically works, not how it makes anyone feel. If this tendency leads Nolan’s critics to label him a chilly filmmaker, there’s the barest hint of knowing silliness to Tenet that warms it up. It plays best when it stops showing us its work and morphs into the fanciest James Bond romp you ever did see, complete with dizzy global location-hopping, car chases that slip and loop like spaghetti, and bespoke tailoring you actually want to reach into the screen and stroke.
