Loved the whole series except the ending of the final episode.
Perhaps Richie should have attempted to take out Eddie leaving Conrad & Maeve seeking revenge in Series 2. Gina should have been with Eddie when this happened, where she is either killed or seriously injured leaving Harry seeking revenge too.
In Series 2, Conrad & Maeve should remain in prison for a while until a new head of family takes over. This could be a battle between Seraphina & Kevin and maybe even Harry.
