15 Most Irritating Subplots In The Dark Knight Trilogy

8. Detective Work (The Dark Knight)

The Subplot: At a crime scene early on in the movie, Batman removes an entire chunk of a wall in order to retrieve a bullet and hopefully find a usable fingerprint. He runs the block through a computer to scan all the shattered fragments of the bullet, and then performs ballistics tests in order to replicate the exact conditions of the bullet shattering in order to ascertain the spread pattern of the fingerprint on the bullet. Phew. Why It's Irritating: While it can barely be characterised as a subplot, it's a several-minute divergence that, aside from adding more needless minutes to the screen time for a relatively minor plot detail, doesn't make a lick of scientific sense. The heat of the bullet being fired would burn the fingerprint (which is largely comprised of oil from the skin) off, not to mention that the shards of bullet would be severely warped from the impact rather than merely being shattered fragments. Sure, suspension of disbelief is one thing, but this isn't just absurd, it's also pretty pointless beyond actually giving Bats a little detective work to do for once.
