Nobody said that the journal should not have published because it is not interesting. You should instead focus on the given argument of "scientific standards" and the Scientific Method, the implicit rule-set of science (to be fair, you can question that too, but you didn't).
A Journal uses peer review to avoid publishing things that do not conform to a certain base level of scientific standard, e.g. comparing the wrong numbers/things, or ignoring causation vs. correlation, drawing the wrong conclusions, etc. A peer is supposed to flag such things and remind the authors of the flaws.
