Temporary exhibits are the most exciting part of any museum, in my opinion. It is within them that you can truly see a museum's value system and curator's perspective in the way in which they choose to situate a unique collection... of art, for example. Susan Power also attributes temporary exhibitions "to attract increasingly larger number of visitors."
The current temporary exhibition at the MAM was certainly crowded during my visit last week. It showcased "over 400 works of art and documents created/displayed in France during the decade bracketing World War II . . . a crucial and tragic moment in the museum's history." The exhibition was organized chronologically, displaying pieces that had been visible at the time, in addition to those that were not. Lighting was low and very little description was given except for blocks of contextual text at the beginning of each section. For this reason I don't think I'd be able to appreciate the amazing juxtaposition of it all--which, I believe, is the most valuable part--had I not been on a guided tour.
