Much has been written and said about the faults of peer review but one thing I think hasn’t been emphasized enough so I’ll state it here: journal editors need to grow a spine. And they need to grow it in two ways, first by not sending obviously flawed studies out for peer review no matter where they come from, then by saying no to reviewers' unreasonable demands, not taking their comments at face value, and sometimes just not waiting 6+ months for a review to come back before making a decision.
