Tenet

The movie never sags in terms of technical elements and even performance. Everyone is committed to Nolan's runaway speed.

...a gorgeous, violent, brilliant puzzle box of a movie that relishes in how convoluted it is, and pays off every second of attention.

Nolan’s desire to stimulate both the blood and the brain feels earnest.

...expands the horizons of the espionage genre.

It may not be 'Back To The Future', but regardless, it has its cake, eats it, then goes back in time and eats it again.
