One can't make good art if one does not enjoy good art. Or to say it another way... you can't be creative if all you think is destructive.
The subject is all that matters, not the technical details. I believe the purpose of photography is to put you in a different place in time. If we're put somewhere uninteresting, we have to critique what we're left with.
I think you're not seeing the forest through the trees. If you want perfection, pick up a paint brush.
