I full agreement with the others here, that this isn't a place to be treated lightly.
One does get the feeling from some of the displays that the Final Solution was a crime against the Polish people rather than the anti-semetic genocide that it actually was.
Nonetheless this does not 'spoil' (for want of better word) what is a heart-wrenching experience.
This is a place that everybody should visit at least once in their lifetime.
