Is it? It seems to be assuming that droid episodes are inherently bad, and moreover that non-droid episodes are thus inherently good. Certainly you are free to conclude that, but it doesnt mean the droid episodes have to be bad, or that non-droid episodes have to be good. It could just as easily be assumed that without the droid episodes, the writers would phone in whichever episodes replaced them in order to focus on the ones they would rather be working on.
