I have to agree with an earlier reviewer that this museum is not "typical". Unfortunately, I really like most museums, so my tastes tend to run toward the "typical" I suppose. First for the pros--definitely not crowded on a Sunday when I visited. Granted it was December, but I was literally the only person in the place for a solid hour. The exhibits are on four floors, and they did have one very interesting and unique exhibit on violence among children that discussed various aspects from bullying to violence in the media, recent events involving guns in schools, etc. Each staircase has a different memorial to victims of the 9/11 attacks as well. But to be honest, I found the museum to be only mediocre due to a few points: 1.) most of the "exhibits" consist of extensive writing on plaques or posters on the walls. Honestly, it would have made for a better book, there was so much reading involved. 2.) Many of the "heroes" highlighted who fought for peace and liberty were actually martyrs, especially the 9/11 victims and those highlighted as fighting for civil rights on the first floor, all of which gave it a kind of depressing air. I felt like most of the time I would read about a person's efforts to bring freedom to their country and the explanation would end with the person being murdered. Lastly, 3.) the two exhibits I was most excited about were very disappointing. The "recreations" of Anne Frank's secret annex and Nelson Mandela's jail cell were easily 12 feet square and each consisted of a bed and a book and little else.

Additionally, I looked up times for the museum about a month ago when I booked my tickets, and since then they changed so that when I arrived I discovered that the museum didn't open for several more hours. I noticed another reviewer mentioned that there was also a lack of communication regarding when it is open, so I would suggest calling ahead.

Final verdict: I'm glad I visited and I learned a few things, enjoyed the unique artwork and several of the exhibits, but I would NOT return, take children under the age of 14, or suggest cutting something else out of your itinerary to fit in the Liberty Museum.
