It is a testimony to both the script and the acting in this film that I watched from beginning to end and was never bored. In Nightingale, which takes place in the home of a man and his mother, we watch this recently returned home veteran come to terms with many of the issues of his life, including his relationships, and the components of his emotional state, namely his wishes, hopes, fears, disappointments, etc. Other people in his life are implied through phone calls and letters. David Oyelowo does a superb acting job in which he travels through different mental states and changes, without going over the top which would have rendered it unbelievable and unwatchable, for me. From beginning to end, he was utterly believable as a man, trying to live, while coming undone.
