Nominated for best film oscar ... seriously?

Rating: 6/10 (8 February 2018)

George Clooney said you can make a bad film out of a good script but you can't make a good film out of a bad script. How could this film be nominated for best film but not be nominated in the screenplay category (Titanic anyone?).
I really wanted to watch this in the cinema and didn't. I made the mistake of buying it on DVD without checking which oscars it was nominated for and now a part of me wished I hadn't.
It isn't by any means a terrible film but I didn't feel emotionally involved with the characters not in the same way as I did with "Saving Private Ryan".
