Great museum, great building, great park around it, great exhibitions and events. just pay attention to your stuff if you take the subway, as the area is quite unsafe. The exhibitions in the gallery are nice, especially the ones on Brazilian landscape / life. True, it's not a huge museum, but it's very good value for money.
