If you'd like to know all the horrific details of that tragic event, you're going to have to pay to watch it on the big screen like the rest of us. Patriots Day , the tale of the Boston Marathon bombing starring Mark "I could have stopped 9/11" Wahlberg is the latest in the new "documentaries are for nerds" genre, in which studios try to make quick buck by shooting the 9 o'clock news. It is far from the only film of its kind we've seen in the last decade. Reliving recent tragedies is suddenly hip in Hollywood. This needs to stop. Here's why.

If the craziness of 2016 has blocked out everything bad that came before, you might not remember all the details of the 2013 Boston Marathon bombing . To summarize, two bombs exploded at the finish line, killing three people and wounding 264 others. For the next four days, Boston and the surrounding area were basically shut down as thousands of police officers and FBI agents searched for the culprits, who were eventually-

5 Making A Movie About An Ongoing Event Affects The Outcome Of That Event

We've told you before about the CSI effect, and how because of the show's highly inaccurate depiction of forensics, juries started expecting the prosecution to be able to prove someone was a murderer because of the unique type of mud on their killing boots. Their expectations were so outrageous that criminals were released because nobody bothered to show them a hair sample. But the glory days of CSI were several NCISs ago. These days, there is a new culprit: the true crime show.

Netflix's unbelievably popular Making A Murderer was fascinating to watch -- so much so that people seemed to forget that it was a piece of entertainment. And entertainment needs a good story and plotline. That might be why the filmmakers left out key details about the case, many of which made Steven Avery look guilty as sin. But viewers assumed they were being given all the information from an unbiased point of view and were sure they had witnessed a gross miscarriage of justice. Soon there were petitions asking President Obama to pardon Avery -- even though a president can only pardon federal prisoners and Avery was convicted by the state of Wisconsin. Similar shows and podcasts like HBO's The Jinx and NPR's Serial all contribute to the collective idea that prosecutors and the police can't be relied upon to get it right, and that the viewer is the one who can really figure out what happened. Because solving a real murder and guessing who the killer is three minutes before Columbo does are the same thing, right?

And sometimes it's just waiting for them and their alibi to both run out of gas.

But at least in those cases, the trials had already happened. What about when movies come out and the case hasn't been closed yet? Unfortunately, we have proof of what effect they have because of the Chris Kyle case. Kyle was the Navy SEAL whose career of headshotting bad guys during the Iraq war was chronicled in American Sniper. Kyle was killed at a gun range by another combat veteran who was suffering from PTSD. That man, Eddie Ray Routh, was put on trial for the murder after the film had already come out. Not only that, but at least two of the jurors had seen the movie. Now, you could argue that seeing a movie that makes the victim out to be an American hero couldn't have that much influence on the outcome of the trial, but you'd probably be wrong. In this case, it took the jurors only three hours to return a verdict, which is ridiculously fast in such a complex case. We'll never know what was said in that jury room, but you have to wonder how often someone declared it was their patriotic duty to avenge the guy from The Hangover.
