Well, I don't get the negative review there. Its a FREE art gallery. So you kind of get more what you pay for right from the get go. You have the option to donate, but you can do that after you view the gallery and determine its donation-worthiness from your point of view.
Granted also that the exhibits are going to change. If you do not like the current exhibit, its no reason to give the VENUE a negative review.
The galleries are situated in a converted warehouse setting, a la The Power Plant, or many such similar modern art venues in Miami. The space is limited, and thus the exhibits can only showcase so much. I was done in under an hour, though most people will probably be done in less time. Keep that in mind when you decide how to spend your day. This is not AGO, so if you are looking to waste an afternoon, you will be disappointed.
There is free street parking available on Givins street (just West of the museum) for 1 hour only - you can be done in that time.
The key thing about this venue is that it's probably a nice place to drop in on if you are already in the area, but not something you should go across the city for.
Enjoy your art.
