I saw three great films in late 2017/early 2018:
Darkest Hour right before Christmas
Dunkirk rented from Amazon right after
And 13 Hours for free on Amazon Prime more recently.
13 Hours, I don’t think, did so well at the box office, but my kids and I all loved it. I thought it to be riveting. If one goes to any video of it on YT regarding the score, etc. everyone is praising the movie. Also the score is top notch, IMO.
