And there was I thinking that it was only railway buffs that were this picky! Having worked on a preserved railway that's been used for many TV programs and films, I learned to stop worrying about details long ago! The one that really got me though was the Network South East seat moquette in Dunkirk, and the fact that the carriage had fluorescent lamps. Some of the costumes the art department have made loco crews wear at out place over the years are just hilarious, not including some of the extra stuff they want hanging off locomotives (such as American style lamps on the front!).
I quite enjoyed Rogue Heroes, but then I also liked all of Peaky Blinders (by the same writer). The TV show did make me go and read the book the series was based on, so if a few people go and do that then I think it's a good thing.
