Season 2- There is to many storylines going on at one time for an hour show. It weighs down the flow and in 5 episodes nothing really happens to keep to story interesting. I guess this is the new story telling because Hotel Portofino is the same way. 5 episodes of rubbish and cram everything in the last episode. Nothing happens in the last episode of World of fire.
If you want a historical war drama do not watch this show. It doesn't even come close to following any factional events of WW2.
