As Tate Modern overhauls the way it presents its collection to the public, critics are beginning to assess the impact of the changes, not just on the Tate, but museums in general. “The wow factor is important to Tate Modern and key to its success, most obviously through the giant works that have held court in the gallery’s Turbine Hall. This is the challenge facing the gallery: to continue to attract all those casual visitors whose imagination has been captured by some of the contemporary shows on display, while also providing for more regular users of art galleries who rightly demand rigour and a certain level of scholarship on their visits.”
