Tenet is Dark in 150 mins. Though the concept of the movie is brilliant and Nolan does a great job with the science stuff but there is very less time to fully understand these concepts and enjoy the movie. The story of the movie is simple but the scientific approach to the movie is confusing and that's why may not be appealing to the masses. While the series Dark relies on similar concepts but it has more than enough episodes to make the audience understand the whole concept which on the other hand Tenet lacks. That's why my rating for Tenet is 3/5..Good but hell of a confusing ride.
