Historical fact is just that.
The dramatic portrayal of those facts by the actors was excellent.
Camera work, scenery, trains, costumes were all great.
Background music was excellent.
Directing and Editing resulted in good cinematic flow.
I found the Jewish accent was disjointed and muffled. Consequently I missed a lot of the dialogue. An English speaking audience only needs a light inflexion of accent.
Apart from that aspect Resistance is a brilliant film.
