This paper critically reviews the entropy model proposed by Adam and Gibbs in 1965 for explaining the dramatic temperature dependence of glass-forming liquids' average relaxation time, one of the most influential models during the last three decades. We discuss the Adam-Gibbs model's theoretical bases as well as the reported experimental model confirmations; in the process of doing this a number of problems with the model are identified.
