Up until the penultimate episode, you always assumed that the other German was going to get it. Werner going made it so much more poignant and was a pivotal moment for Mike as well.The last episode was just brilliant. Brilliant. Werner and Mike - so poignant and then finishing off with Jimmy transforming into Saul which has looked likely this entire series. But there it was. I'm going to miss this and I really hope we get another series.
Kim's realisation at the end was heartbreaking as well.
Think there's enough loose ends to justify another series but whilst I would be gutted not to get another one, I would be 'satisfied' if it ended now.
