Critical Wave, later subtitled "The European Science Fiction & Fantasy Review", was a British small-press magazine, initially published and co-edited by Steve Green and Martin Tudor during the period 1987-96. There was also a short-lived US edition in the late 1980s. Despite the immense enthusiasm displayed by many of its readers, Critical Wave only continued to appear with extensive financial input from its editors and key supporters. It eventually buckled under the pressure of increasing print costs, postage and bank charges, and announced its closure in late 1996.
