I'll break it down in a couple of bullet points. 1. Science is hard. 2. There is no such thing as a perfect study. Every method/methodology has weaknesses. Look for converging evidence across multiple studies which use different designs. 3. Initial studies often do not have the funding needed to do things as optimally as possible in a single study, but they do provide evidence for ideas that can be pursued further. 4. It is often socially safer to point out deficiencies than to praise strengths. Same as snobs raining down on you when you say you like some midrange wine. 5. Often issues will be raised that are already acknowledged by the authors. 6. Complaints are often based on inaccurate news reporting, not actual research. 7. Science is hard.
