Not necessarily. Ignoring crap may be a better strategy than picking it apart.

Cooperation is also easier when different groups in the same research area don't try too hard to invalidate each other's claims. If the problem in question is interesting you're much better off writing your own paper on it with your own claims and results. You can dismiss the other paper with a single paragraph: "Contrary to the findings of I.C. Wiener in [2] we observe that..." and leave it at that.

The system is entirely broken but I don't see an easy way to make it better.
