First, what can go wrong if you put together great actors from series like Lost, Orange is the new black, Prison break and Sons of Anarchy?.. The answer is a little bittersweet.
Second, I love William Fincher as an actor but I think Kim Koates is actually on fire and a step over him. Just watch him on Bad Blood series.
Lastly, the script here is a kind of a bittersweet harmony. The movie starts pretty well but end in a mess with no explanations about what you have watched.
So, overall a good movie with great actors but a weak script. A bittersweet symphony.
