I am writing this review in the future to keep people from repeating my mistake in the past, which was to watch this movie in the first place.
Some pros: multicultural cast though just one woman in a familiar role in the movie. Cons: the rest.
Tenet has Americans fighting with the Russians in one battle scene after another with some gobbledygook thrown in about a weapon that can go from the future to the present, etc. Basically, the film has a convoluted, complicated plot; is absent of a theme but most importantly has no heart. And as a consequence all the fighting, all the pseudo-science comes off as meaningless and cold. If you want to reintroduce movie theaters back into your life save yourself for another movie, hopefully one with not only battle scene after battle scene but a movie that registers a pulse as well.
