I think it depends why it's made and how it will be perceived...

But I guess a reminder that only 70 years ago (around a lifetime, compare that with your grand parents life) they was a terrible conflict and war with what is nowadays our "neighbors"...

So I think it can be a good sign for younger generations (if only they would care, but honestly I think they are more into celebrities shows, and other craps).
I also think they might not be capable of really realizing what it was without actually experiencing that.*

*I did not experience that and I only have visited a few places, read books, and seen private letters, been in bunkers, etc... I have a hint on how terrible it was but it's definitely a light version of what happened.
