Fraser Hannay’s review published on Letterboxd:
Rewatching Tenet really solidified all my problems with it. I don't have any patience for this movie. Nolan's greatest failing is that, despite the onslaught of expensive looking action, the underlying stakes are never once clear. There are a lot of cool "things" happening the entire time, but I find myself wondering where the tension is, and why I should care. Even my second time through, there are countless moments in which the logistics are explained, but the actual objective, the suspense, is lost in the execution. This problem is only exacerbated by the lack of real humanity in any of the characters, so the emotional stakes are also absent.
The best way I can explain Tenet, is that it's like watching people play a complex game while you yourself know none of the rules. It's evident that there are thoughtful plays being made, but without that firm grounding, none of it means anything.
