I know any architect is not without issues, some of their buildings will be amazing, and others just not work. Everyone will have a different experience of the building, and a building which may be loved by many may feel all wrong to someone else.
I really enjoy some Frank Gehry building, because of the sense of play and the way the design encourages the exploration of the building from the outside before you walk in. The drama builds before you even see the content of the building.
I have only been able to visit a small number of his buildings, but I have enjoyed them.
I think there are ideas of changing how people look at things and think about them in his best work.
