Much better than anticipated, it uses its limited floor space well. It also does not try to be pretentiously secretive about the history and facts, you will leave knowing more than when you went in, and you will be affected if you decide to go through all the drawers in the violent killings room.
The demonstration and political violence parts are just slightly biased, but only ever so slightly, which in truth is much more objective than I had expected.
Overall a good experience, I would say 2-3 hours can be spent there.
