One of my Jewish French friends says that there’s a general ignorance among her French acquaintances about Judaism’s religious traditions, history, and so on. Sort of like “Purim? Is that a brand of soap?”
Thus, the purpose of this museum is to educate the public. Sort of like “Everything You Ever Wanted to Know about Judaism, But Were Afraid Would Be Too Boring to Ask About (And Guess What – You’re Right!)” Not that Judaism is boring, but seriously, if you have even the slightest exposure to Jewish culture (e.g., if you’ve been in New York City for more than ten minutes), most of the exhibitions will be painfully basic. Even more disappointingly, there is little focus on French Judaism in particular, with the exception of some medieval tombstones and a display on the Dreypus affair.
In short – go to the Holocaust Memorial instead.
