I dont mind the plot-heavy approach, but I found it convoluted and detached. It didnt help that half the dialogue was mumbled or overpowered by other sounds. It moved at ADD pace and never really took the time to develop a sense of tension or stakes. Unlike say the recent Mission Impossible movies which move at breakneck speed but know when to slow it down to build up to one of the big action set pieces. Maybe Tenet will improve on a second viewing but I was pretty uninvested in it, a pity given how fantastic the concept is.
