If you haven't watched the TV series, skip this movie. It's a meaningful epilogue to the Ray Donovan series but would probably be frustrating otherwise. The film was less exciting than the series because it did flashback a lot- more than needed- but filled in blanks that were important in understanding the main relationship between ray and mick. It concluded things in a way, but the end wasn't quite final, was it? Maybe we'll see RD again.
