I've not read everything in this thread cos really can't be bothered tbh, so might be repeating what people have already said.
Enjoying it but it lacks focus. Down The Line is better as there's a sort of 'Who's next?' aspect to it and more of an element of surprise. And the 'What is point?' bloke is missing (though I heard him briefly at start of episode 2) and he is the best character! That obviously wouldn't work on TV though. Or would it?
Afinkawin was right about the ghostly episode of Down The Line and episode like that (more themed) work better as it almost rolls into sitcom territory, which works well. (That episode is brill, btw, if people haven't heard it) and there was a genuine cliff-hanger that didn't get resolved until the following series.
I'll keep watching this as it's relatively entertaining. Hopefully, some 'ongoing' threads will go across episodes and stuff may build from that. The Nazi/Socialist sisters are great though; I hope they do that justice over the series.
