The problem with 'based on a true story' movies

Rating: 6/10 (8 June 2019)

12 Strong stars Chris Hemsworth in a movie about a team of American Soldiers who attempt to take down the taliban. And i was....ok, a decent movie with great chemistry amongst the main cast, good individual performances and immersive war action. However, the narrative doesn't do anyone much favours, these bio-pics that are supposedly based on real events really do struggle with creating drama and intensity because the real events are often not that interesting. I am not doubting the significance and sacrifices of the real people behind this very real event but from an entertainment standpoint there really wasn't much source material to create a wholesome narrative.
Like many films of the same tagline this movie has that one punchline that the rest of the narrative has to surround, in this case '12 men' vs the taliban. It is an interesting story but not enough to be a feature length film, and it was a long movie over 2 hours. I definitely felt that run time, a lot of filler and unnecessary parts that built little character and barely progressing the story. Unfortunately not a great movie, but maybe acceptable on first viewing.
