Boring and tedious, with no real depth. Seemed to be music video like in style, some ok scenes that felt like The Prestige which remided you that you were watching a Nolan in places. Having initially hated Tenet - as forgot to actually watch in the correct way - bluray with imax ratios is the only way!... I was pining for some complexity and ambition - which makes Tenet a masterpiece and bafflingly good in comparsion to how dull Opp is. If youre reading this Nolan - please keep making films like Tenet. DK, Inception! Very surpising how it won so many awards etc. Almost as bad as Barbie tbh (maybe quite similar in an odd way). It was nothing like how it seemed from the trailer. Didn't go to any depths about the actual subject matter or science/ engineering, was more about the characters and politics involved and flipped about loosing your concentration and just felt music video like in pace.
