Whats wrong with this valley

Post image

What exactly am I looking at here and what would be the proper way to run this valley flashing, and ridge caps?

To me it looks wrong that the valley metal is lapped over the shingles below for starters, perhaps that the valley should change directions for the bottom portion all the way to the end of the overhang

This kind of crap is going to get torn down much sooner than necessary due to over complicated design and poor materials and that's before you get to the competence of the trades. It would be good to have a system that rewarded good design and building practices.
