World War 2 ... it is not just the war that was abhorent ... it is how human beings were treated. Please do not compare yourself to what especially Jews had to go through, if you decide by choice to not listen to medical experts - that is just one example of how people nowadays like to distort history.
Now that aside, there are cliches here and some predictable plot twists. But overall it is quite the engaging human story. Even when certain other twists are ... well hard to understand to say the least. But ... it is what it is and I reckon we are human after all, even if it doesn't always seem that way (in this case when being a Nazi - never forget that some if not most were brainwashed into believing certain things ... which would be a more apt comparison for those thinking themselves as victims, but let's not delve more into that).
It is a bit long and I reckon has certain pacing flaws, but the question is how much you are willing to cut it some slack for the message and the endurance of the main characters ... so in the end as always it will be up to you ...
