Firstly, this is all spoken in Polish but has English subtitles if selected. The acting and dialogue are excellent and it's easy for an English speaking viewer to understand. The sets, uniforms and vehicles are all very authentic looking, as are the action scenes set during World War Two. The story is both very intelligent and interesting and shows the varying viewpoints of the characters' intentions in a balanced way. The story takes place mainly in occupied Warsaw - the attention to detail is very impressive and occasional real WW2 black & white film of Warsaw is blended in for a few seconds between scenes to very good effect. The characters are very believable and there's a good balance between build-up, action, character development and the occasional love interests amongst the resistance fighters and the Jewish victims in the Warsaw ghetto as well.
The cost of the box set might seem expensive, but there are a total of 13 episodes (44 minutes each episode plus credits) over 4 discs. I've watched many WW2 films (including the excellent Scandinavian ones) and Czas Honoru (Time Of Honour) ranks up there at the top.
