Popular literature has always been raising many different emotions and research issues. One of the research groups, represented by Piotr Kowalski, criticized popular literature thoroughly. A new wave of scientists emerged in the nineties. They tried out different research methods, criticizing popular literature (especially fantasy) much less than might be expected. This met with a huge degrees of scepticism from Kowalski who did not agree with those methods and tried to prove them wrong in his two last publications. This article presents Kowalski's views, in the meantime trying to argue with them.
