Oldman shines in this 1/2 a story

Rating: 6/10 (24 August 2018)

Did anyone else feel like this was 1/2 a movie. Gary Oldman shines as Churchill, and I want to know more of the man portrayed herein. But I felt like it was 1/2 a story. When the credits started rolling it was like, that's it? What about the rest of Churchill's darkest hour? Surely this didn't cover 1/2!
I wanted a movie about Churchill the man specifically regarding the role he played throughout WWII. Here we got through Dunkirk... roll credits.
