Is most of SW above criticism.

Why do I ask that question, you may or may not ask?

Because the prequels, couldn't possibly live up to the first star wars. Therefore they couldn't be as good. So there's almost no point in providing critique for them.

And the sequel trilogy couldn't possibly be even as good as the prequels(sadly enough), for all their faults.

... even though the prequels have more faults than you can shake a stick at.

So there's almost no point in having critique for those as well.
