The fact you called it dumb threw any credability you had out the window. Thanks for playing.
Bruce quit being Batman for 8 years and let his company slide into decline because a supervillain killed his girlfriend = Dumb
Alfred leaves Bruce when he needs his support the most = Dumb
Bane's voice and the whole misdirection of him possibly being the son of Ra's al Ghul (which isn't pronounced "Raz" no matter how much Nolan want's to insist it is) = Dumb
A device/program which erases your digital footprint from every computer in the world = Dumb
Sending all the police in the city into the sewers all at one time = Dumb
The fact that Batman is so easily tricked and does the dumbest thing possible in nearly every situation = Dumb
Bat auto pilot foreshadowing and use as plot device to build false expectation that Batman was going to die when he was obviously not = Dumb
Creating a character called John Blake as an amalgamation of Jason, Dick and Tim and then still having to drill home to the audience that his middle name is Robin = unbelievably fucking Dumb
Bruce creating a fusion energy device and then abandoning it when he "finds out" that it could be weaponized = Dumb (but working on the basis that Bruce in the Nolan films is a complete moron maybe expected)
An unguarded prison designed like a well, but that nobody (except Talia and Bruce) has ever escaped from, even though the prisoners are shown to have multiple lengths of rope at their disposal = Dumb
I could go on like this for about 7 pages but you get the idea. The movie is dumb, it trys to come off as smart and realistic but it isn't.
