(Updated review) Recommend, but does require some base knowledge of real events

Rating: 7/10 (17 April 2020)

I'm 1 hour and 15 mins in and still 1.5 hours to go. I have no idea where this is going, but if nothing is happening in 10 minutes, I'm giving up. And for someone who doesn't like movies lasting more than 1.5 hours, I really think I'm giving it my best shot.

Ok, I finished the whole movie (taking a break an picking it back up the next day). And yes, in the end I do really enjoy how this movie unfolded. Yes, it starts out slow, but a slow setup was needed to have it all come together in the end.
I must say, I started watching this without knowing anything about the back story and not even realising this was partly based on real-life events (I guess I was slow picking up on that). Once I realised that, I had to google a lot of characters and events to make sense of it all. But to me, that was worth it and made it all the more interesting. And it puts the ending on such a different light.
So yes, conclusion is that I did enjoy this movie after all, but it does require some base knowledge. Bumped it up from 5 stars to 7 stars.
