8. How Did Bane Find Applied Sciences? - The Dark Knight Rises (2012)
Though
The Dark Knight Rises emerged as one of the most plot hole-ridden movies of 2011, most of the errors that have been associated with Christopher Nolan's final Batman installment just come down to one thing: lazy screenwriting. A few of said plot holes, however, are legitimate in the world of the movie - we're just never gifted with an answer as to how certain events occur. Take Batman's return to Gotham from halfway across the world, for example, which isn't a plot hole necessarily: we just never find out how it does it. But one particular plot thread that was left in the dark (and should have been explained for narrative purposes) concerns Bane's discovery of Applied Sciences. For reasons that are never unveiled, Bane manages to find the exact location of a top secret underground facility that only Bruce Wayne and Lucius Fox are aware of. Even Miranda Tate, who is revealed to be working aside Bane, is unaware of its location. At first, this discovery is treated as though it'll be worked into the plot at a later point - but no such explanation ever comes. Bane's source is left unidentified.
