I've always been a fan of Brutalism, but I've never really been a huge fan of the Science Center. I think it's a little too much of a mish-mash of angles and shapes, that never really comes together in any harmonious way. I much prefer the institutional examples like CBE that are more structured and rectilinear.
The problem is when you get too much concrete on concrete everywhere (overly-brutalist plazas tend to suck imo). The best brutalism is when its surrounded by lush greenery or things to contrast the concrete.
