Real talk: the yelp reviews don't lie - it's a superb museum experience.
It's a very interactive place, and you feel like part of the art when you're there. My favorites were the third floor and the Pablo Valbuena exhibit that Grant B. mentions in his review. There are lots of exhibits to take a look at, yet it's a manageable couple hour visit.
Make sure to walk around the local neighborhood's war streets (or whatever they are called), since it's such a cool area.
